Welcome to Splitsville, population you.

If Crystal Bowersox really wanted to lay blame for not winning “American Idol,” she could put it on her boyfriend. Bowersox said yesterday they broke up by mutual decision — and it was on Tuesday morning.  That was the day of Bowersox’s last chance to perform for votes on “Idol.”

She says “Big Tony” was a small-town guy and didn’t like the Hollywood lifestyle, while Bowersox is ready for a big career. Bowersox says the breakup “put that fire in my belly” for her performance. She says she’s not mad at her ex and they’ll be friends for a long time.

Boy is he’s gonna be pissed when she makes her first mil.
