We know it was hot this weekend, but the L.A.M.B. designer must have something a little more family-appropriate in her closet than a see-thru shirt that shows off her bra!

Gwen and Gavin took the kids to a family party in the Valley on Sunday, after attending Brad Grey's A-list wedding with Brad Pitt, Tom Cruise & Katie Holmes and Jennifer Lopez on Saturday.

But Gwen wasn't the only one in the Stefani-Rossdale family to rock the mesh look -- check out what Kingston was wearing ... after the jump.

Lady Gaga tweeted this bizarre picture of herself as a motorcycle over the weekend, the cover art for her new album Born This Way.

Gaga, whose new single Judas leaked online last week, has previously released an alien-like promo pic for her upcoming album, but she seems to be trading in her weird prosthetics for some chrome and steel!

With a caption that reads "COVER BY NICK KNIGHT AND THE HAUS OF GAGA 5 † 23 † 11", Gaga also wrote, "can't wait for you to hear the music!"

And if you think this is bizarre, click below to see the "special edition" cover!




Okay, so Miley Cyrus didn't actually drop while she was shopping yesterday, but she certainly dropped some dough!

The teen queen had her purchases at American Rag brought to her car and a source inside the store tells X17online she dropped what "must have been at least a few thousand dollars in about 20 minutes."

Sheesh! Girl must get some allowance!

Marriage looks good on Reese Witherspoon! At the New York premiere of Water for Elephants, the newlywed wore a white, balloon-skirt dress by Jason Wu, while Rob Pattinson wore whatever suit he wore and looked hot in it!

As Rob just finished wrapping the next installment in the Twilight series, Breaking Dawn, he's free to embark on a whirlwind, worldwide tour with Reese to promote Elephants, which opens April 22.

Talk about a busy guy! You think Reese will have to leave her new hubby Jim Toth behind while she does press?

After watching the game from inside her Mercedes G-Wagon last week, Britney Spears emerged to see Sean Preston batter up at the baseball diamond Sunday.

Jason Trawick escorted his lovely lady -- who was wearing a bright spring floral print with wedge heels -- and even bought a Coke for her to sip in the sunny Valley heat.

Meanwhile, daddy Kevin Federline gave Sean some batting tips ...





It appears the couple's love of soda has rubbed off on Sean! Jayden, however, found another way to cool off ...



Adorable!

Demi Moore and Ashton Kutcher weren't feelin' the love for photographers last night after they emerged from the Arclight movie theater.

Ashton couldn't bring himself to put a smile on his face and Demi couldn't even bring herself to show her face ... in fact, when asked why she wouldn't answer any of our questions, she said, "Because you're f-ing a-holes."

That's the spirit, Demi!

Christina Aguilera's boyfriend Matthew Rutler got some good news this week - the LA County District Attorney officially rejected the DUI case against him, citing insufficient evidence.

Rutler, 25, was stopped by police and arrested last month on suspicion of DUI and Aguilera was booked on a misdemeanor charge of public intoxication after a boozy dinner at their favorite restaurant, Osteria Mozza.

Selma Blair put on a poofy muumuu to cover her baby bump yesterday while running errands in Beverly Hills.

Kinda cute with the ruffles, but probably not the best choice of maternity wear. Hey, Nicole Richie, why don't you design a line of pregnancy clothes for hip moms?! These ladies need some better options!
