Christina Aguilera`s wild girls` trip was precursor to divorce

New York: Christina Aguilera``s marriage ended after the star went for a girls-only vacation with Nicole Richie and Samantha Ronson in Cabo San Lucas, Mexico, last month, it has emerged.

Sources say "there were already problems between her and her husband, but things got worse after her wild girls` trip."

Insiders say Aguilera and music executive Jordan Bratman, married for five years, spent hardly any time together while she was on set for her movie, "Burlesque."

"Although Jordan and I are separated, our commitment to our son, Max, remains as strong as ever," the New York Post quoted Aguilera as saying.
