Pop tart Britney Spears and Christina Aguilera reportedly 'kissed and made up' last month after Brit's baby was born. Aguilera allegedly dissed Brit pretty hard during pregnancy when Spears was packing on the pounds, saying "She'd let herself go."
Aguilera later denied those reports, but now Christina is at it again if a report from the American tabloid 'The Star' is to believed.
And reportedly-the shot at Brit came last month at the lavish wedding between Chris and new hubby Jordan Bratman late last month!
Overheard at the ceremony, Aguilera reportedly ripped into Britney about her wild hubby Kevin Federline!
'Several guests' heard the blonde newlywed "Express gratitude that she wasn't marrying a devoted womanizer like Britney's estranged hubby Kevin Federline who was recently spotted in Las Vegas partying without Brit.
Though guests said she took the shot in a 'joking manner' the buzz was "why even bring up the old feud" especially on her wedding day.
