They're getting ready to become a family!

Chris Pratt picked up son Jack, whom he shares with ex-wife Anna Faris, for dinner with his new fiancee Katherine Schwarzenegger last night. The trio dined in Santa Monica and appeared totally comfortable and happy together. Katherine, 29, will be a first-time mom to Chris' boy, and we're going to go out on a limb and predict the new couple will have more children of their own together.

Meanwhile, Faris has been nothing but supportive of Chris' relationship with Kate. She congratulated them on Instagram after news of their engagement and she happily gives Jack over to his dad to spend time with him and Schwarzenegger. The couple even have in their divorce settlement the agreement that they'll live within five miles of each other while Jack's in elementary school. How smart!

Another Wednesday night at church ... alone! Hailey Baldwin has been riding solo often, as of late, with hubby Justin Bieber out of town. Question is -- where is he and why?

A source tells X17online JB's just up north at the couple's Ontario, Canada home so that he can get some space -- space from LA, and marriage and Hailey. He's been suffering from some sort of issue for which he's been seeking treatment at Amen Clinic, a "brain health" treatment center. Perhaps he's doing a more intense therapy north of the border so that he can come home healthy and in a better mindset.

Meanwhile, Hailey's holding down the fort back home -- she's keeping up with her marital duties of settling in the couple's new home, organizing their upcoming wedding, and still going to Hillsong every Wednesday night as her therapy.

As usual, Kourtney Kardashian was also at Hillsong's service last night. We wonder if it's difficult for Hailey to have Justin's exes around all the time! That said, Hails is friends with the whole Kardashian clan because of her connection with fellow model Kendall, so maybe it's not a big deal. Also in attendance was none other than Lana del Rey! Interestingly, nee Elizabeth Grant, grew up Catholic, going to Catholic school and singing in her church's choir. So maybe it's not a huge leap to join Hillsong with their music-based worship ... still, we were surprised to see her there!

We bet this is some SERIOUS money, b*tches!

Cardi B is laughing her Bronx butt aaallllll the way to the BANK! The singer just announced a residency at the Palms Resort & Casino in Las Vegas at the hotel's posh new nightclub KAOS. The club is amphitheater-style and functions as a day-time performance venue and a nightclub and opens in April.

And if Cardi seems like a pretty big, pretty current name to be taking on Vegas (Sin City is no longer a place where aging performers go to make bank and die) ... check out the fact that DRAKE -- yes DRAKE! -- signed a $10 million-deal to perform at the Wynn's club XS Nightclub. Wha?!

Vegas is really heating up and competition among the clubs is fierce ... and the talent is even fiercer! G-Eazy, Skrillex, Kaskade and Above & Beyond are also booked to appear exclusively at KAOS.

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 ...
