While DLB kept pretty under the radar at the hip joint, we're told one of his fellow companions caused a stir for all the wrong reasons...
Relax Glambert fans, it was Ke$ha, obviously.
The wannabe rebel singer performed two songs at the club, "Tik Tok" and "Blah Blah Blah," around 3 a.m. and a partyer tells us it was "awful."
Blame it on the alcohol?
"She said she wasn't drunk, but that she was going to get drunk later," says our unimpressed party spy.
"She wore some ugly shiny one-piece mess and sounded just off-key and growly."
Yikes—not the best review for an up-and-comer. You can tell this girl thinks she's already Lady Gaga status, which FYI, she so is not.
Apparently everyone at Club 57 agreed Ke$ha was "unappealing," especially during "Blah Blah Blah" where, in between the sporadic claps and cheers, we're told everyone was really whispering 'bout how bad she sounded.
Side note: After seeing her at Clive Davis' pre-Grammy party the other week, lets just say none of this is breaking news.
The real stud you're all wondering about, Mr. Lambert, held court with fellow power gay Dustin Lance Black in the VIP section upstairs.
Our source says A.L. looked his usual fabulous eyelinered self, but "didn't mix with anyone in the regular crowd."
Another stud-muffin semi-more in-tune to the ways of common folk was...
Mark Wahlberg, humpy 'n' pumped in a white tee walking out of the Beverly Hills Hotel over the weekend.
Marky Mark, who loves to brunch there at the Polo Lounge, strutted his sexy pecs out of the pink hotel and over to his black convertible Bentley...which he parked on the side street of the hotel.
Too funny, don't you love it when celebs who can afford a $200,000 somethin' car skimp out on valet? Hey—can't say we blame ya, babe! That stuff's way too overpriced in this town.
