The Desperate Housewives star and Cruz – baby brother of Penélope Cruz – headed to Mexico with some pals this week.
The pair strolled on the beach in Mazatlan and later had lunch with the governor of the Sinaloa state, Mario Lopez Valdez.
That night, they flew to Cabo where they’re expected to stay for a few days. And so far, the trip is going exceptionally well, says a source.
“Things are getting very serious between Eva and Eduardo,” the source says. “They’re really happy.”
