Christina AguileraSince divorcing Jordan Bratman last fall, Christina Aguilera has been in a spiral that those close to her are calling out of control.

Following her national anthem flub at the Super Bowl, she took a tumble at the Grammys, was caught having sex with boyfriend Matthew Rutler in a bathroom during a family event, sued for copyright infringement and most recently, was arrested for public drunkenness.

And while the struggling singer hasn't addressed her issues publicly, sources close to Aguilera are speaking out.

In the March 21 issue of Star, an insider is claiming that Aguilera has hit rock bottom. "Christina's lost her confidence since she split from Jordan. She gets terribly sad, and that's when all the awful memories come flooding back and she ends up numbing herself with booze and food."
