Little Nori and cousin Penelope partied it up on Sunday at a little kids' party in Beverly Hills, escorted by Kourtney Kardashian and these two tykes' party attire was on fleek!

Nori had a jewel-collared turtleneck with cuffed jeans, black high-top Vans and her hair in adorable princess French braids. Penelope had on a tulle tutu, silver Mary-Janes and a cotton biker jacket. Kourtney was casual with a denim jacket draped over her shoulders, topped off with a black leather cap.

The trio joined friends at a home where Kourtney and Kim have taken their kids many times for mommy-and-me classes. Nori held a daisy in her hand -- it was unclear whether it was a fashion accessory or, perhaps, a hostess gift. Either way, it's darn cute!

Kourtney's been kicking in lots of free babysitting hours while sis Kim rests and home with new baby boy Saint. We can't wait to see him!

We love us some Caitlyn Jenner but we are NOT feeling this business-casual look for a night at the movies ...

And by the way, why is Cait's long-time pal Ronda holding the car door for the transgender star and acting like her bodyguard/handler? These two used to be neighbors and friends and since Bruce's transition to Cait, it seems like Ronda's become the reality star's little b*tch!

OR the other possibility is that Ronda and Caitlyn are dating ... that's what some people say and that's the question we asked that REALLY pissed off Ms. Jenner. She told our photographer to F-off.

Now Caitlyn, immediately after her transition, said she wasn't sure whether she'd go for guys or girls. She's always seemed unusually close to pal Candis Cayne, but is it possible the previously-pixie-cropped Kamihira with her new long locks has caught the eye of Caitlyn in a new way now that she's a lady?

What the hell?! Is Justin Bieber hiding some love bites on his neck with this thick hoodie?

After his third of fourth date with Kourtney Kardashian Friday night at The Nice Guy, we now see The Biebs covering his neck as he heads out for a pressed juice with a pal. Now we would say NO WAY is the pop star, 21, hooking up with the mother-of-three, 36, but Us Weekly would! The mag says Bieber's even bragging about it!

"Oh yeah, that’s definitely happening and has been for some time now. Every time Kourtney and Justin are together they’re extremely flirtatious. They text each other all the time," a source tells the magazine.

Seriously?!

Kendall Jenner shared a laugh with family friend Harry Hudson, on Saturday, after the two finished a shopping trip to Barnes & Noble in Calabasas. We've seen this dude a few times before -- most recently, comforting Kylie after she temporarily split from long-time boyfriend Tyga, back on November 16. Seems like a cool dude -- and the Jenner girls' loyalty to the up-and-coming pop star runs deep. Harry was diagnosed with Hodgkin's lymphoma in 2013 and Kendall and Kylie have stuck by him through months of chemotherapy and beyond. The budding singer can now focus on his music career again, now that he's healthy -- check out his music HERE.

Meanwhile, Kendall's feeling maternal, it appears -- she posted this adorable Instagram with nephew Reign Disick yesterday and captioned it, "Me as a mom." Aww!

Taylor Swift celebrates her 26th birthday today and her pals are wishing her well on social media, as you would expect from her squad! We caught up with her Saturday, as she touched down at LAX, and asked her about beau Calvin Harris, to which she responded ... with silence. These two are either OVER or they're really keeping their private lives on the DL ...

Meanwhile, the signer's pal Selena Gomez posted a cute montage pic of the two of them and captioned it "I don't know life without you Taylor. Happy birthday!"

Jaime King - for whom Swift plays the role of godmother to her youngest child - posted this message: "Dear Tay - Tomorrow is your birthday and I will be in the air. This picture I took of you brings back the fondest of memories. It captures all of your beauty that I know, that the world knows, in one photograph. You have the uncanny ability to just get straight into the Soul’s of us all in one shot.”

But perhaps the cutest of all was Taylor's own Instagram -- this pic, captioned: "Today I bgin my 26th year of freaking out over stuff." Adorbs!

Eva Longoria just got an early Christmas gift -- a red ruby engagement ring from boyfriend Jose Antonio Baston!

Apparently the couple became betrothed in Dubai, where the Desperate Housewives star, 40, and her businessman boyfriend, 46, are attending the Global Gift Foundation event. The actress captioned the photo, "Ummmm so this happened. #Engaged #Dubai #Happiness"

The pair started dating in November 2013. Baston is the president of Televisa, Latin America's largest media company and the world's largest Spanish-language media conglomerate. Oh ... and did we mention ... he's HOT! Congrats to the beautiful couple!

I wish I were Kylie Jenner's dog ... seriously. Cute, skinny and chauffeured around in a Rolls Royce!

The youngest of the Kardashian-Jenner clan took her Italian greyhound pooch Sophia for some Christmas shopping at Saks Fifth Avenue in Beverly Hills, on Friday. Kylie's obviously checking off people on her gift list -- which must be pretty damn long. Wonder if Tyga's on that list or not. Hmmm ... naughty or nice? What do YOU think?

Check this out ... Miley Cyrus dressed as a baby, singing about how much she hates baby talk in her new single BB Talk with pal Wayne Coyne of The Flaming Lips -- her band Miley Cyrus & Her Dead Petz. The lyrics go something like this:

"Your baby talk is creeping me out / F—k me so you stop baby talking,” she sings. “You know, like, I hate all that f—king PDA, I probably hate it more than your f--king friends do / You know, it's sweet and you couldn't be more opposite of my last dickhead but I don't know if I can get over / the f—king goo."

Uh ....
