Pop superstar Christina Aguilera has dismissed reports she is expecting her first child with husband JORDAN BRATMAN.

An employee of Beverly Hills, California children's store Bellini claimed the DIRRTY singer discussed her pregnancy while shopping for baby clothes with Bratman.

The sales assistant was reported to have said: "(Aguilera) came in with her husband, and he sat in one of the big chairs and let her do her shopping. They said they don't know what they're having.

"They seemed really excited. She was talking to (another customer) and she said she took a home pregnancy test and that it was positive. She kept saying they'd have to come back when they knew the sex of the baby."

However, a spokeswoman for 26-year-old Aguilera denies the shopping trip ever took place: "She said it is not true and she wasn't in Bellini."
