Just another example of how divorce (and by association marriage) ruins people: recently divorced superstar Christina Aguilara was arrested last night.

The ‘Burlesque’ star, who filed for divorce in October of 2010, has been on a rampage of embarrassments the last few months, from screwing up the National Anthem at the Super Bowl to falling on her ass at the Grammy’s, to allegedly having sex in the bathroom at her parent’s parties a couple weeks ago and just generally being wasted 24 hours a day. And it all came to its zenith early this morning when the singer was arrested in Hollywood for public intoxication. According to TMZ, after her boyfriend was pulled over for driving under the influence and arrested, the cops determined that she was “extremely intoxicated” … and since she was “unable to care for herself,” she too was taken into custody.

Her boyfriend, Matthew Rutler, had his bail set at $30,000 for his misdemeanor DUI. Sources say they’ve been trying to get Christina into rehab for weeks, so hopefully this is the nail in her don’t-turn-into-Snooki coffin.
