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.

An onlooker at the time said: "Christina looked really off-colour. She walked into the restaurant with her hand on her stomach and didn't look very happy at all."

However her spokesperson has stepped forward to clarify the reason behind Aguilera's vomiting, explaining: "She has had stomach flu all week.

"She is not pregnant."
