Valentine's Day 2008

JOHN MAYER, 30

This singer-songwriter – and blogger extraordinaire – needs a new lady to be his muse.

Whom Should He Date?
• Cameron Diaz, 35: Their brief fling fizzled – but she loves musicians, he loves blonde actresses and together they could be Hollywood's next power couple.
• Jessica Simpson, 27: After his ex was blamed for beau Tony Romo's bad football performance, he defended her passionately on his blog. Could there still be lingering feelings?
• Alicia Keys, 28: Both are respected, multitalented musicians. The only question would be, "Where to put all the Grammys?"
