Anna Nicole Smith's former boyfriend LARRY BIRKHEAD has fallen for another troubled star - Britney Spears. The photojournalist, who is the father of Smith's baby girl Dannielynn, has confessed to a crush on Toxic singer Spears. He tells American magazine In Touch Weekly, "I think Britney is sexy." A pal tells the latest issue of the publication, "Larry has a thing for vulnerable blondes - and no one seems more vulnerable than Britney these days." And the friend insists Birkhead feels Spears would be his ideal match: "Larry wants to find someone who already has kids so they can raise their families together, just like the Brady Bunch."
