CHRISTINA STAYING AWAY FROM JORDAN UNTIL EVERYTHING IS FIGURED OUT

Now that Christina Aguilera isn't hiding her relationship with BF and former Burlesque set assistant Matthew Rutler anymore, it seems the newbie lovers are free to get as serious as they want. (Well, as serious as they can, since her divorce isn't finalized.)

And they have been!

A source tells E! News that Xtina and Matt have already shacked up together, in greasy, grand splendor!

We hear that, prior to Christina embarking on her European Burlesque tour, the love birds had been staying in a bungalow together at the gorgeous Beverly Hills Hotel.

Apparently, Christina was spotted roaming the grounds—one posh gal lunching at the famed Polo Lounge swears she spotted Xtina's bright blonde hair darting in through the lobby recently.

More importantly, we're told she and Matt opted for cozy nights in.

"She ordered a lot of room service," spills the source. "She loves fried food—chicken fingers, burgers, pizza. They spent a lot of time in their room eating and hanging out."

Let's hope it's not just Aguilera springing for the $600-plus-a-night bungalow. Don't the nicer dudes these days at least offer to go dutch?

The comparisons to Britney Spears and Kevin Federline have already started (and the fried food won't help), true. But we will say Xtina seems happier than B.S. was during her Kevin association.

Or is it just that Brit-Brit's bald/umbrella moments during her divorce doomed the "good times" with K-Fed forever?

Whatever. Aguilera's hubby, Jordan Bratman, is currently living in the guest house of their Beverly Hills mansion only a few miles away, we're told.

"She's trying to stay away from him until they figure everything out," adds the Christina insider. Aguilera filed for divorce on October 14.

We've contacted Christina's rep, who has not commented.
