Singer Lily Allen was once expelled from school for channeling her inner Antonella Barba.

Yes, she was suspended for being a mediocre singer.

Not!

But seriously folks. What got the British singing sensation in trouble way back when was her penchant for performing sex acts at recess. Really.

In a recent interview, Lily Allen revealed that back in the day, she got kicked out of school for:

"Doing things that I shouldn't have been doing with boys that I shouldn't have been doing at that young age. Smoking cigarettes, drinking."

It's better than crashing one's car (*cough* Lindsay Lohan) when coked up and drunk. When pushed about what she was doing with boys, Allen laughed:

"I was giving blow jobs."

Move over, Kelis. You and your milkshake have company.

Sadly, when asked for more details, Lily Allen's lips - unlike back on the ol' playground - were uncharacteristically sealed.

"I don't want to go into it," she said. "It's not good."

Lily apparently meant it when she said she was more of a bad girl than pseudo-rival alt-Brit pop star Amy Winehouse.

Heck, Amy is an old married lady who can't stop singing the praises of Blake Fielder-Civil. She's practically over the hill!
