The "Dirrty" girl is back but in a good way! Christina was all over her loyal husband at the Back to Basics album launch on Tuesday at Marquee showing off her sexy moves that would make any girl blush. At least it was with her husband - sounds like a healthy relationship to me. She is making sure we all know she's still got the nasty in her. Does this mean we can call her Xtina again? The Gatecrasher reports:

She was all over hubby Jordan Bratman at her "Back to Basics" album launch at Marquee Tuesday, showing off moves that would make Gypsy Rose Lee blush.

At one point, pal Marc Jacobs presented her with an oversized shopping bag containing what appeared to be his entire fall collection of handbags.

In return, she presented Jacobs with a campy young gentleman, and the two were observed getting down together to Whitney Houston's "I Wanna Dance With Somebody" and Journey's "Don't Stop Believin'."

Later, Mr. Bratman proved he's more than just a lust object. As his better half did interviews, he waited loyally on the sideline, holding her itsy-bitsy pink bag.

Lucky girl. I want to score all of MJs fall bags and then have a personal hand bag carrier. Sounds like Christina is enjoying being back in the limelight.

Lots more sexy pics of Christina so
