A-Rod swings for actress Cameron Diaz

New York Yankees slugger Alex Rodriguez and actress Cameron Diaz had a series of secret dates following their flirtation at a Super Bowl party in February, the New York Post reported Wednesday.

The couple secretly saw each other in Florida while A-Rod was at spring training, according to U.S. tabloid magazine Life & Style.

"A-Rod's with Cameron. They've been keeping it quiet, but they're totally together," a source told the weekly.

Witnesses at the Creative Artists Agency Super Bowl party described them as flirting and dancing before leaving together at the end of the night. But a source told the Post that their relationship is casual, with neither pushing for commitment.

A-Rod tried to dispel his ladies' man reputation after splitting from Kate Hudson last year, following a highly publicized breakup with Madonna in early 2009.

Despite that, he was linked to a series of Miami beauties including Elaine Spottswood and gorgeous Wilhelmina model Melissa B.

Reps for A-Rod and Diaz could not be reached for comment.
