It's Criss Angel!

We got clean cut Criss Monday night at his charity event in Vegas, where he lost the eyeliner ... and his long locks.

The event was for pediatric cancer research -- his toddler son, Johnny, was diagnosed with the disease last fall.

Johnny was front and center with dad ... in high spirits.

Taylor Swift tagged along with BFF Gigi Hadid and her BF, Zayn Malik, in NYC ... all by her lonesome.

The serial dater rode solo with the couple as they left Gigi's apartment.

Leo DiCaprio couldn't turn down a tiny request.

Leo gave 1 lucky fan the ultimate selfie at the U.S. Open final and even gave her final cut powers.

Emily Ratajkowski's boobs were holding on for dear life at Fashion Week.

The model gave her pair quite a breather while attending Harper's Bazaar's "ICONS By Carine Roitfeld" celebration over the weekend at The Plaza Hotel in NYC.

Monday's off to a great start ...

Lady Gaga's full of crop tops in London, which means she's letting almost everything hang out.

Gaga left Capital London early Friday morning with a giant denim wedgie -- and cup of coffee.

She's got a new song out, and if this is how she's gonna promote, we say ... keep plugging away, Gaga!

Tyga juuust missed getting into a jam most guys would pay to experience -- trapped in an elevator with Kendall and Kylie Jenner -- until NY's Bravest came to their rescue.

Kylie, her sis and some friends were leaving an apartment Thursday evening, when their lift got stuck. Unclear how long they were hanging out in there, but firefighters were able to get them out safely.

Based on the you-know-what eatin' grin on Tyga's face -- who greeted them when they got out -- everyone got over it pretty quickly.

Nothing screams, "I'm good" ... like Snapchatting your way through a crisis.

Grown ass women can dream of owning one -- meanwhile, North West's already taking her Louis Vuitton for a spin around the playground.

Okay, we don't know where North really went with her high-priced purse, but Kim and Kanye's 3-year-old was flossing big time in NYC Thursday.

For those of you still dreaming ... looks like her LV retails for just under a grand.

Side note: Even her driver's got Yeezys.

Ashley Graham and Bella Hadid strutted their stuff Tuesday night ... and they brought different assets to the table.

The models were at London's Tate Modern for the GQ Men of Year Awards 2016, and while Bella is certainly a babe ... Ashley clearly has more curve appeal.

Each girl is beautiful, and there's no point in arguing. But just for the sake of discussion, let's just ask ...

Wilmer Valderrama and Minka Kelly need a vacay from their vacay, 'cause nothing about their faces says rested after a weekend trip to Mexico.

The one-time exes looked pretty officially back together as they boarded a plane Monday in Cabo San Lucas. We're guessing the getaway included some relaxation -- we saw 'em lounging by the pool -- but sleep appears to be a whole other story.

Catching ZZZs is overrated ... when you've got a hot piece.

When Beyonce wants her guests to rock 1970s getups for her birthday ... best believe they fall into formation.

Queen Bey turned 35 over the weekend, but come Monday, she threw herself a Sooouuuuuul Train-themed rooftop party at The Nomad Hotel in NYC. All the celebs in attendance turned out in '70s gear ... and then hit the dance floor to get their groove on.

Some of those stars included Diddy and Cassie, Kendrick Lamar, Usher, Michelle Williams, Kelly Rowland and Alicia Keys. And, of course, Jay was by her side gettin' down.

Bey was the true star of the show though, reminding everyone who they were celebrating.

North West proved she's her mother Kim Kadashian's daughter down to the matching $11k disco ball dresses they wore to Kanye's Monday show at Madison Square Garden.

It was North's first official concert and Kim made sure her kid was dressed to impress. Interesting choice on the shoes though ... no Yeezys.

It's technically still summer, so North still gets a pass on curfew.

Lindsay Lohan is out in Greece showing off a new ring ... and it doesn't look a thing like the engagement rock she got from ex-fiance Egor Tarabasov.

Bikini-clad Lindsay was in Mykonos this week with a yellow gem on her left ring finger. She's reportedly been hanging in Greece with restaurant owner Dennis Papageorgiou ... fueling rumors she's moving on from Egor after their blowout fight.

Y'know what Egor's thinking -- where the hell's my emerald??!!

Khloe Kardashian has a brand new star athlete in her life ... Cleveland Cavaliers stud Tristan Thompson.

The two have been spending some serious quality time together recently ... and Thursday, they were spotted at a mansion in Beverly Hills ... flaunting their impressive physiques.

Unclear if they're friends ... or more ... but we did see them out at Bootsy Bellows nightclub together over the weekend ... and they left the club within minutes of each other.

One thing's clear ... they definitely look good together.

Sofia Richie doesn't need to wear Justin Bieber's shirts to prove they're a thing ... she just rocks his pants instead.

JB's gf was out in WeHo Thursday rocking a cropped top and official Purpose Tour sweatpants.

Even without Justin, Sofia's still reppin' her boo. Keeper material?

Wilmer Valderrama and Minka Kelly seem to be rekindling an old flame, and it's already getting really hot.

The exes grabbed a spicy meal at Palms Thai Restaurant in Hollywood -- before leaving in Wilmer's ride. Note the perfect gentleman move with the car door.

Minka and Wilmer used to be an item in 2012 ... shortly after she split with Derek Jeter. Wilmer just broke up with Demi Lovato a couple months ago -- so this time he's the one rebounding.

And doing it well.

Saint West is showing off his birthright -- those near-impossible to come by baby Yeezys.

Kim and Kanye's tot was cruising around the Big Apple Thursday afternoon ... looking like the most adorable billboard for his pop's kicks, which sold out instantly this week.

Retail price is $130 for a pair, but the 8-month-old probably got the friends and fam discount.

Good to be the Saint.
