Aguilera: I'm not pregnant!

A bout of stomach flu was behind Christina Aguilera's recent vomiting on a night out with her boyfriend Jordan Bratman - not an alleged pregnancy.

The Dirrty singer threw up outside her limousine on the way to a romantic meal with Bratman at Toscana's Italian restaurant in Brentwood, California, which led to tabloid speculation the star was expecting her first child.
