27 looks good on Adele ... real good.

The reclusive singer came out of hiding this week, taking over the Internet with her new song, "Hello." She hit up BBC radio for a promotional stop in London as she gets ready to release her new album, "25."

As good as 19 and 21 were -- 27's already looking epic for her.

After a round of surfing Thursday afternoon in Los Angeles, Luke Wilson toweled off ... revealing a trimmed down frame.

C'mon, Mitch ... "We're going streaking!"

Kenny Chesney broke from his country roots Thursday by spending the day in Malibu, paddle boarding and competing in a game of shirtless bocce ball.

The country star was hanging with some friends, including super surfer Laird Hamilton.

By the way ... Kenny's 47.

Christina Milian and Lil Wayne still have their hands all over each other, a month after their break-up ... but it's all in a day's work.

Wayne grinded with a barely dressed Christina on the set of her new music video for "Do It." The video was shot last week in Miami and judging by photos it's hard to believe it's more business than pleasure.

Still, sources tell us they aren't getting back together, but remain friends ... so working this closely is not a problem. We're told the chemistry will always be there.

Easy to see why ...

Justin Bieber has figured it out ... when you're young and rich, hookups beat relationships every time.

Justin was hanging Wednesday at a pub in London with Elysandra Quinones, one of his backup dancers.

It's not hard to figure out the rest of the night.

Caitlyn Jenner is learning all about girl problems ... like hiding those pesky tracks in her hairpiece.

Bob Barker is on the road to recovery after splitting his head open while on a walk near his home.

Barker was spotted out in West Hollywood on Wednesday and you can see the bandaged up wound on his right temple.

TMZ broke the story, 91-year-old Barker was taken to an L.A. hospital after going down during a morning walk. Lucky for Bob, cops were in the area and stopped to help him until paramedics arrived.

We're told Bob's knee was also injured in the fall. We're betting he can still take Sandler.

Michael J. Fox was out in New York City on Wednesday morning -- aka "Back to the Future" Day -- sporting a pair of shoes he probably laced himself and getting into a car that does not go back in time.

For the uninitiated, October 21, 2015 is the date Marty McFly (Fox's character in the sequel) travels to when he goes into the future with Doc Brown to save his son from being arrested.

The movie's vision of the future included flying cars, self-drying jackets and the Chicago Cubs winning the World Series ... none of which is a reality this year.

Duty calls for Kendall and Kylie Jenner -- days after brother-in-law Lamar Odom's brush with death -- Kendall punched in for work, while her sis showed up for support.

The Jenner girls attended the Balmain x H&M launch event in NYC, where Kendall modeled on the catwalk. Kylie watched from the front row.

Both flew to Lamar’s bedside last week, and now that he's back in LA. and slowly improving ... it looks like Kendall and Kylie are getting back to everyday life. As much as possible, anyway.

Ob-la-di, ob-la-da ...

Kate Upton banged out a set of squats during a workout in West Hollywood with her personal trainer, who kept a watchful eye on ... her form.

Yes, he's actually getting paid to do this.

Chiwetel Ejiofor ... ahh who cares -- his new girlfriend is awesome!

The "12 Years a Slave" star took a stroll Tuesday in NYC with the stunning babe ... safe to say she's in head-to-head competition with the Oscar nominated actor ... 'cause she has a nice head.

It's the second time they've been spotted together ... they showed up at "The Martian" premiere as well. So far we don't know her name.

Nick Jonas and Kate Hudson have shown all the signs of being coupled up -- traveling together, dining together, even Disney-ing together -- right up until she gripped another dude in NYC.

Kate was on her way to a premiere Monday night hand-in-hand with the other guy ... who, btw, happens to be her agent -- and also happens to have been spotted holding Kate tight multiple times in recent months.

Yes, Jonas and Hudson were spotted together in multiple places last month, and as recently as last weekend.

So, who's really winning the Kate sweepstakes? Since people in the know tell us Nick and Kate weren't dating, just hooking up -- we'll guess BOTH for the block.

Lewis Hamilton has a need for speed ... even on the sidewalk.

The Formula 1 racer ditched his Mercedes for a different ride -- a Ninebot electric unicycle, which he rode while walking his adorable bulldog Roscoe over the weekend in Miami.

Diana Ross got several rolls of Charmin back in her arms again Sunday afternoon as she hit up a CVS in Bev Hills.

Chris Martin and new GF Annabelle Wallis couldn't keep their hands off each other Saturday afternoon in Paris ... kissing and dancing in the streets.

The Coldplay singer and the "Peaky Blinders" star have been dating since August, not long after Martin split with Jennifer Lawrence.

Gwyneth, Jennifer and Annabelle ... he definitely has a type.

Tyga is re-living the glory days when Kylie was by his side as she studied for her high school exams ... like 3 months ago.

Tyga and his 18-year-old GF were in downtown L.A. Friday night shooting a music video. The theme is becoming predictable, right?
