Larry Birkhead has a crush on Britney Spears, IN TOUCH WEEKLY reports.

“I think Britney is sexy,” Larry tells In Touch.

The insider says, “Larry has a thing for vulnerable blondes — and no one seems more vulnerable than Britney these days,” adding that Larry, 34, finds being a single dad challenging, and is looking to date a single woman with children. “Larry wants to find someone who already has kids so they can raise their families together, just like the Brady Bunch,” his pal says. According to an insider, “He’s trying hard to get fixed up with Britney.” Like Larry’s ex Anna Nicole Smith, Britney, 26, is a Southern blonde bombshell.
