Congrats! Carrie Underwood and hubby Mike Fisher and their 3-year-old son Isaiah welcomed baby #2 -- a boy, Jacob Bryan Fisher -- on Monday. The happy couple took the Instagram to share the happy news and pix are ADORABLE!

In one shot, the Nashville Predators, 38, player holds baby Jacob and in another, son Isaiah has his baby brother on his lap as he sits in a chair. Meanwhile, Carrie, 35, posted a natural shot of her cuddling her newborn with a fresh, no-makeup face. The country music star's scar was barely visible (just saying, since Carrie's scar ALWAYS has to be mentioned).

Underwood had suffered three miscarriages -- so the caption on her Instagram birth announcement had special meaning: "Jacob Bryan Fisher entered the world in the wee hours of the morning on Monday...his mom, dad and big brother couldn’t be happier for God to trust them with taking care of this little miracle! Our hearts are full, our eyes are tired and our lives are forever changed. Life is good..."

❤️Fifty Five and smiling from the inside out.... Finally back to the original 1964. Living in a body free of breast implants, fillers, botox, exstensions and all the bullshit I thought I needed in order to keep up with what society conditioned me to believe what a sexy woman should look like until the toxicity of it all almost killed me.......... Your health is your wealth so please make educated decisions, research the partial information you’re given by our broken system before putting anything foreign in your body. It took me many years of undoing some bad choices I made for myself before I finally found the freedom to sustainable internal beauty and acceptance of what is the best version of myself by nobody’s standards but my own.........................It’s on us to learn to love our selves and celebrate our unique, one of a kind beauty at all ages as we move through this journey called “life”. Beauty has no meaning without your health................... #ShamelessSelfie #55 #BeautyStartsFromWithin #AgeComesWithWisdom

Yolanda Hadid is showing off her TRUE self -- at least according to the caption of this selfie!

The 55-year-old former model wrote: "Living in a body free of breast implants, fillers, botox, extensions and all the bullshit I thought I needed in order to keep up with what society conditioned me to believe what a sexy woman should look like until the toxicity of it all almost killed me." Hadid has been suffering from Lyme disease for years -- a struggle that famously broke up her marriage to David Foster during taping of Real Housewives of Beverly Hills.

Of course her kids -- Gigi, Bella and Anwar -- are all models and skeptics have always speculated that youngest daughter Bella has had plastic surgery. When commenters suggested that on Yolanda's recent post, the mama bear wasn't havin' it! She clapped back: "None of my children have have [ever] done fillers or Botox or put anything foreign in their bodies. They know better after seeing what I went through."

In fact, during RHOBH taping, she said Bella also suffers from Lyme disease. Still, last time we checked, that doesn't affect how your nose looks. And yes, we realize people's faces change as they get older -- particularly from pre-teen years into their twenties, but NO plastic surgery? Really? Actually, read carefully and Yolanda doesn't say Bella hasn't had a nose job ... just that she doesn't have anything "foreign" in her body. But a nose job doesn't count!

Beautiful! The girl AND the ring :)

Katherine Schwarzenegger flashed her gorgeous cushion-cut diamond engagement ring from fiance Chris PrattM as she hit the grocery store in Brentwood, on Tuesday.

The 29-year-old daughter of Arnold Schwarzenegger and Maria Shriver -- author of I Just Graduated, Now What? and Rock What You've Got -- wore a casual, all-black look, topped off with a cozy sherpa jacket for an outing to the supermarket. And of course she carried hemp recyclable bags!

Mom Maria was on The Today Show Tuesday morning and was, of course, asked about her daughter's engagement to which she replied that she's not allowed to talk about it because "it's not my moment!" Still, we have a feeling this cute couple's going to become everybody's moment because fans just can't get enough of them! Wedding watchers, stay tuned!

Chris Brown isn't gonna take this lying down ... the singer claims he'll sue for defamation the model who claims Brown raped her in his Paris Hotel room earlier this week. The claim sent Chris into police custody for 24 hours and made headlines around the world for a guy famous for beating ex-girlfriend Rihanna back in 2009.

Brown was released without charges Tuesday after being questioned overnight by French police -- but Paris officials reserve the right to file charges at a later time, dependent on their investigation.

The 29-year-old's French lawyer, Raphael Chiche, said Brown vigorously denied the allegations and he is preparing to file the defamation lawsuit on behalf of his client: "A complaint for slanderous denunciation will be filed tomorrow with the public prosecutor of Paris."

A 24-year-old model -- not named for privacy reasons -- claims the singer and two other men raped her during a drug-fueled party in Brown's hotel suite at the Mandarin Oriental in Paris a week ago.

Chris Brown is calling B.S. on a woman who's made a claim of sexual assault against the singer in France. Brown was taken into police custody and held for 24 hours following an accusation of rape by a woman who says the singer took her back to his hotel room at the Mandarin Oriental in Paris following an evening nightclubbing, where he, his bodyguard and another unnamed person allegedly assaulted the woman.

Brown wrote, along with a graphic reading "The B!tch Lyin'!," "I WANNA MAKE IT PERFECTLY CLEAR,. THIS IS FALSE AND A WHOLE LOT OF CAP [sic]! NNNNNNNNEEEEEEEEEEVVVVVVVVVVEEEEEERRRRRR!!!!!! FOR MY DAUGHTER AND MY FAMILY THIS IS SO DISPRESPECTFUL AND IS AGAINST MY CHARACTER AND MORALS!!!!!"

French policed are still investigating, according to a TMZ report: "The investigations, which are not closed at this stage, will continue under the authority of the Paris prosecutor’s office." The state could still decide to press charges, which means for now, Chris can't leave France ...

OH SNAP! Chris' attorney must have told him to remove this unfavorable post from Instagram, but plenty of people screen-grabbed it ...

Talk about being conflicted! Seems Gwyneth Paltrow is really just doing the best she can in her efforts to save the environment ... the Goop guru has a Tesla, after all!

But she and new hubby Brad Falchuk and their kids all took a private jet to Cabo for the MLK holiday weekend which didn't exactly help with their carbon footprint. But hey, what are they supposed to do? Fly commercial?!

The Clean Plate author and her clan were south of the border celebrating Billionaire Boys Club producer pal Crystal Lourd's birthday. The pair wore matching silver sequined spaghetti-strap dresses for a Mexico blowout -- the photo of which Gwen captioned: "Well, you did it again @cl5star!' Thank you for your incredible generosity, spirit and sparkles."

Gwen's and Brad's kids were along for the ride, enjoying the long weekend out of school. Moses is a spitting of his dad Chris Martin and Apple didn't fall far from her mother's tree!

Is Kanye West finally on his way to realizing his dream of being "one of the biggest real estate developers of all time?" Seems so!

The rapper-artist-designer-conceptualist met with a partner at his Calabasas studio and discussed his inspiration board for Yeezy Home -- talking social-impact design for prefabricated concrete homes that Ye envisions as the housing of the future. West is also planning a 5-home community on a 300-acre tract he owns in in the tony San Fernando Valley neighborhood.

Kanye's initial renderings were released last summer after his now infamous interview with Charlamagne The God, in which he claimed he basically be the next Donald Trump ...

The designs were a collaboration with some architecture students who envisioned a concrete pre-fab home for the masses -- a low-cost living design that coincided with Kanye Tweeting, "We’re starting a Yeezy architecture arm called Yeezy home. We’re looking for architects and industrial designers who want to make the world better.”

A better world, indeed! Ye's taking this seriously -- he was burning the midnight oil Monday night, again at his studio to work his design process. Hey, if anyone can do it, Kanye can!

Netflix has done it! The streaming service scored it's first-ever Best Picture nomination from the Academy for Alfonso Cuaron's nostalgic black-and-white drama about his childhood in Mexico City. In fact, the film picked up a whopping ten nominations for the 2019 Oscars, along with British period drama The Favourite."

Meanwhile, Marvel film Black Panther is the first superhero film to ever be nominated for Best Picture. Rounding out that category are Lady Gaga and Bradley Cooper's A Star Is Born, Spike Lee's Blackkklansman, the Queen/Freddie Mercury biopic Bohemian Rhapsody, Mahershala Ali and Viggo Mortensen's Green Book, Christian Bale's Dick Cheney story Vice, and The Favourite.

Gaga gets a nod for Best Actress for A Star Is Born, going up against favorite Glenn Close for The Wife. Bale is the likely winner for Best Actor for his transformative portrayal of Cheney in Vice but he'll go up against Cooper for A Star Is Born. Will Spike Lee finally win an Oscar? Honestly, it'll likely go to critics' favorite Cuaron for Roma even though the Blackkklansman director is more than worth!

Click through to see the full list of nominees ... The 2019 Oscars ceremony will be broadcast live on Feb. 24 at 8 p.m. ET/5 p.m. PT on ABC.
