The Desperate Housewives star has been seen out multiple times with Eduardo Cruz, baby brother of Penélope Cruz, recently. One tabloid reports that he has been spending time at her home as well.
Reps aren't commenting on whether there's a simmering romance, but just last Wednesday they enjoyed a "flirty" night out watching the flamenco group Sir Sultry at the cabaret venue Café Was.
"Eva and Eduardo seemed to have a good time together," a fellow diner tells PEOPLE. "They were flirty, and held hands for a brief moment during the performance. Eva looked very happy and acted like a single girl that is ready for some fun."
Cruz, 25, and Longoria, 35, enjoyed dinner during the show – joined by a girlfriend of hers – and the onlooker says the actress looked happy and healthy.
"She looked very pretty with barely any makeup and she seemed to very much enjoy spending her evening with Eduardo," the diner says.
At the end of the night, the pair split up, with Cruz leaving out the back and catching a ride with Longoria's friend.
Two days later, Longoria was back on the Desperate Housewives set, where, a source says, she seems to be doing better than ever.
"Eva definitely seems to have moved on from her sad divorce drama," the source says. "Lately, she acts happier and more focused on the set."
Longoria was also spotted with Cruz in October leaving her Hollywood restaurant, Beso.
