The pop star and baseball player, whose respective marriages both recently ended, were in town as Madonna performed a concert for her "Sticky and Sweet" tour Saturday night and Rodriguez offered a baseball clinic to poor kids in a new park Sunday.

Asked by reporters how he felt about being in Mexico City at the same time Madonna is there, E! quoted him as saying, "Very good."

"Expect to see Madonna and Alex together a lot more," a tour source told the entertainment news program. "She wants to take some time off and spend a lot of it with Alex."

Although rumors Madonna and Rodriguez have been seeing each other have been swirling for months, the pair has not publicly confirmed their alleged romance.
