Sounds like Eva Longoria and her new boyfriend Jose Antonio Baston were heating up the party scene at Art Basel over the weekend!

The couple attended Haute Living and Hublot's The Art of Fusion party on Friday, Dec. 6 in Miami, where the twosome was unafraid to flaunt their love for each other, with an eyewitness telling E! News the duo walked into the event holding hands and they were seen kissing all night.

"They looked like such a great couple," an insider tells E! News of the pair, who reportedly first started seeing each other in October. "She looks so happy and he is so madly in love with her."

While the former Desperate Housewives star was seemingly enjoying the spotlight at the party, smiling from ear to ear as she posed for pics in a pair of black leather pants, a crisp white blouse and red pointed toe pumps, her man was not nearly as comfortable with the cameras, according to the eyewitness, and instead let his ladylove take center stage.

"He wants her to be in the spotlight," the source adds of Baston, who is the president of Televisa, Latin America's largest media company. "He clearly looked uncomfortable when the attention was on them. He loved it when it was just him and Eva."

Other celebs at the event, which was presented by Dom Perignon, included Kim Kardashian's BFF Jonathan Cheban, as well as former Real Housewives of New York star Jill Zarin, Lenny Kravitz and Serena Williams

A rep for the 38-year-old actress confirmed to E! News last month that Longoria is indeed dating Baston, 45, after the couple was photographed together attending the Museo Jumex Opening dinner at Casa De La Bola in Mexico City, Mexico on Nov. 15.

Longoria was last romantically linked to Ready for Love reality star Ernesto Argüello. The twosome split in August.
