TEXAS (SS): Eva Longoria has hit the jackpot with her new boyfriend. The actress is dating Jose “Pepe” Antonio Baston - the 45-year-old president of Televisa, the largest media company in Latin America. And the star is convinced she has found her Mr. Right. Eva, sources say, positively glowed at his side in a body-hugging dress at an event in Mexico City on Nov 15. “They seemed very comfortable together and clearly enjoyed each other’s company,” revealed an insider. It’s believed Eva’s pal, Melanie Griffith, helped her find a new man.
