Gaga Parties With Mystery Monster!

Lady G celebrates her Grammy wins with an unidentified “little monster”

Though it doesn't hold a candle to Beyoncé's record-setting night, after winning two Grammy Awards Lady Gaga proved she is probably still the most wanted woman in the Biz right now.

Gaga hit up the Interscope afterparty in Santa Monica last night and was hard to miss, wearing only the nude glittered body suit you see pictured under this silver jacket here. How Britney Spears circa Toxic era, no? Oh, and she was still rocking the gigantic headpiece too, mind you.

So who was rolling in Lady Gaga's entourage? A too-cool-for-school blogger, "Papa" Joe Simpson, and…

A dapper-looking mystery blond gentleman.

First things first, could Lady G have taken a "little monster" for herself? If you remember back in December, Gaga was having her fun with a boy-toy at Hyde club in Hollywood, cozying up and dancing with a guy in an equally outrageous getup.

The man in question from last night was def dressed "normal" in a black suit and had his arm around L.G. for most of the night (when she wasn't being introduced to all the Industry types there, that is).

So the question remains—lover, handler or one of Gaga's gays?

It's always hard to tell what type of relaysh is going on with L.G., since she's got tons of gay-BFF's in her crew, but onlookers tell us the blond twosome looked "cute and coupley" as they laughed quite closely and played with some of the food on their table.

Perhaps it was just one of her gay besties who only looked so damn straight since flamboyant Gaga hanger-oner Perez Hilton was a few feet away, holding court like he was the star of the evening.

Howevs, one dude gave him the attention he so desperately wanted, rushing right up to say hello…Joe Simpson!

Uh, we don't think daughters Jessica or Ashlee (aka Ass-lee, as Perez calls her) would be too happy about their chummy encounter.

We'll take the scheming for what it's worth and bet Papa Joe is trying to get in good with the friends so he can get to Gaga. Professionally, of course.
