Summer

Sasha Obama's summer job at a Martha's Vineyard restaurant is going to cramp her style in a big way, thanks to a slew of child labor laws.

We did some checking, and there are a bunch of things Massachusetts prohibits the president's 15-year-old daughter from doing at Nancy's Restaurant. Among them, she can't:

-- cook on an open flame

-- operate pressure cookers, broilers, food slicers, cutters or mixers

-- bake anything ... period

-- operate microwaves that heat above 140 degrees

-- transport grease hotter than 100 degrees

-- work in freezers or meat coolers

-- wash windows higher than 10 feet from ground level

And this is interesting. We've spoken with people who were at Nancy's when Sasha was there, and they say there was no visible evidence of security. We're told no one was searched and nothing seemed out of the ordinary.

Justin Bieber just broke his "no photos" rule in a big way ... letting an obscure rap duo shoot a rap video in his castle.

The Biebs recently ran into a guy named BB the Jerk, a member of the L.A. rap duo These White Kids. Turns out Justin's a big fan of the duo's YouTube videos. The next thing BB knew, he and his rap partner were partying at Bieber's pool party.

At the party BB casually mentioned he had a new song called "Michael Phelps" and Justin suggested they get a video camera on the spot and shoot the music video for the song.

The video features hot chicks, of course, Bieber jumping fully clothed into the pool and there's even a cameo with Brazilian superstar Neymar Jr.

Looks like the 2016 Rio Olympics may have a new anthem.

Dwyane Wade bolted Miami for Chicago ... but he's still kickin' it off the court with superstar ex-Heat teammate and BFF Chris Bosh ... bro-ing out at C.B.'s Malibu mansion.

The former teammates linked up in the 'Bu Wednesday for some quality man time ... gettin' in a bunch of activities, from jammin' out on the drums and guitar to hiking (while their wives tagged along and drank sangria).

If anyone thought there was a drop of bad blood between D. Wade and Bosh ... this video surely puts that to rest.

Britney Spears mixed business with pleasure this week flying to Hawaii on the heels of her new album announcement.

David Guetta's got major dirt on his GF, and she's got it on him too ... 'cause it's just what ya do in Ibiza.

The EDM superstar and Jessica Ledon went mudding on one of the islands near Ibiza ... just like Kate Hudson did a couple weeks ago.

No, Chrissy Teigen is not on vacation in Hawaii, but she's definitely hanging loose with John Legend ... and 3-month-old baby Luna.

The ridiculously gorgeous fam is chilling on a yacht off St. Tropez ... like a ton of other celebs this week. We're guessing Luna and John are big fans of mama Teigen's outfit.

Mom boobs -- they're not just for kids.

Kourtney Kardashian's got her brood a crazy Nantucket estate for July ... and Scott's there too!

Kourtney's rented out a 7 bedroom, 8 bath Cape Cod pad, and it's pretty spectacular. The pics were enticing enough for Scott to ask if he could tag along, and Kourt obliged.

The house goes for $6,600 a night, but we're told Airbnb hooked Kourtney up.

East Coast, beware ... you've been invaded.

It's been a year and half since Cristiano Ronaldo and bikini model Irina Shayk broke up -- but they're each doing okay ... with Shayk chillin' with Bradley Cooper in Italy and CR7 partying with Eva Longoria in Spain.

Irina and Bradley have been together since April 2015 -- though they haven't spoken publicly about their relationship.

Ronaldo, on the other hand, hasn't settled down at all -- and has been spotted out with all sorts of different ladies since the big split.

He's currently in Ibiza -- where he ran into Eva Longoria.

But the real love of Ronaldo's life ... himself ... the dude takes more selfies than Paris Hilton -- and recently busted out the selfie stick to get the perfect angle on his yacht.

Enjoy the eye candy.

Christina Milian's popping out of her swimsuit, in all the right places ... and we don't mean Ibiza.

The singer's doing a little vacay, and possibly a little shopping, for a swimsuit that will provide better boob coverage.

Lady Gaga looked surprisingly comfortable with a solid and snug wedgie as she lounged poolside in Cabo.

Brazilian model Adriana Lima's Greek vacation was like a mini Euro Cup of hotness with a lot of girl-on-girl action.

Lima turned up on the beaches of Mykonos vacationing alongside Polish football star Robert Lewandowski, his wife, Anna, and German baller Sami Khedira. Neither of their national teams made it to Sunday's Euro Cup final, but they're still winners judging by the photos.

The model who accused Chris Brown of assaulting her has surfaced again ... this time on the beaches of Miami with the bare minimum of clothing.

Liziane Gutierrez accused Brown of punching her earlier this year during a party in Las Vegas. No criminal charges were filed, though she's filed a lawsuit against him.

Carrie Underwood slipped into her best neon pink and soaked up some rays in Mexico.

Carrie and her hubby, NHL star Mike Fisher, are vacationing in Cabo. Check out the pics ... Carrie couldn't look hotter and brighter.

Justin Bieber's new gal pal has a striking resemblance ... to one Selena Gomez.

The Biebs was chillin' with Puerto Rican model Alexandra Rodriguez on a yacht down in Miami. Hard to tell ... but she might be wearing his swim trunks ... which doesn't do her any justice. Check out the pics below ... Alexandra can wear the hell out of a red bikini.

Justin definitely knows how to ride.

If 6'6'' 265-pound Rob Gronkowski shows up to your house, you better have plenty of extra taco meat.

Luckily for Jeff Ballard -- former rep for Charlie Sheen, Zac Efron and Johnny Depp -- he was well-stocked when he got a text from a buddy asking if he could bring a "random" +1 to taco night.

Gronk was in town and decided to swing by the Sherman Oaks backyard party with a mutual friend of Ballard's. Rob crushed 15 carne asada and chicken tacos with the works. We're told normal humans only threw down 2 or 3.

Gronk stayed for almost two hours, throwing a football around with the guests and chilling poolside. Most shockingly, we're told Rob rejected Coronas and opted for water.

Demi Lovato made sure the rays caught all her good parts while lounging poolside in Miami.

We'd say she looked bent out of shape over her recent breakup with longtime BF Wilmer Valderrama, but these pics prove otherwise.
