Aguilera Dishes

Some things a pop star just can't do?:

CHRISTINA AGUILERA has warned pop rival BRITNEY SPEARS not to expect a comeback after her baby is born - because she's "let herself go" too much to reclaim her sex symbol status.

There is some merit in this worry, but it's not about having a baby: Britney's knees may be too badly-damaged to keep the dancepop star status. But having kids? It's nothing: look at Madonna!
