Tony Parker's loss is Eduardo Cruz's gain.

Eva Longoria, who split from the Spurs point guard last year and started dating Penelope Cruz's brother in January, was spotted south of the border with her new man this week. They vacationed in Mexico with a few friends.

The couple is currently in Cabo and a friend tells People we're looking at a lot more than a fling.

"Things are getting very serious between Eva and Eduardo," the source says. "They're really happy."
