The Desperate Housewives star beamed for the camera in a classy, form-fitting, sleeved, black-and-white body-con dress. She completed her sophisticated ensemble with pointed stiletto pumps and a black, satin clutch with gold hardware.
Baston, meanwhile, is a worthy match for the Devious Maids producer: The business executive is president of Televisa, Latin America's largest media company, and the world's largest Spanish-speaking media conglomerate, according to his official biography page for the company.
Longoria and her new love were first spotted kissing and holding hands in NYC in late October. The source adds to Us, "They have been spending a lot of time together and like each other a lot."
Prior to dating Baston, she was linked to Miami-based entrepreneur Ernesto Arguello -- who was ironically selected as a bachelor contestant on Longoria's reality TV series, Ready for Love. The two called it quits in August after four months of dating, as first reported by Us. "It wasn't that serious," a source told Us of Longoria's relationship with the contestant. "He was fun."
Prior to Arguello, Longoria dated NFL quarterback Mark Sanchez and Penelope Cruz's brother Eduardo Cruz. The beautiful star dated Cruz on-and-off-again for about one year, after they first got together in February 2011 -- several months after the actress signed off on her divorce from NBA player Tony Parker, her husband of 4 years.
