Tea Leoni is dating her "Madam Secretary" co-star and on-screen husband Tim Daly, Us Weekly reports. A source tells the site of the couple, "Their chemistry on set is electrifying. They have an amazing time filming."

An eyewitness reveals to the site that Tea and Tim were seen strolling down a street in Los Angeles' Venice area "with their arms wrapped around each other" on Friday, November 14. The eyewitness adds, "They were definitely couple-y."

Back in September, Tim gushed about working with Tea on "Madam Secretary" in an interview with Collider. "It's great. It's so funny, [Tea and I] went to the same high school, years apart. It was a very unique boarding school in Vermont," he said.

He added of Tea, "She's a person, like me and like a lot of people who have gone to that school, including my own daughter, who can be perfectly happy sleeping in a wet sleeping bag on a stone floor, or staying in a fancy hotel. She's not a whiner. She wants to work hard and she wants to have fun."

"[Tea and I] get along really, really well," he continued, "We have a really good time. I've gotten along with plenty of people, but the chemistry sucked. And I've hated people where the chemistry is great. It's much better if you get along and the chemistry is good. That's perfect."

Tea and Tim's romance comes four months after her divorce from her ex-husband David Duchovny was finalized. Tim, meanwhile, got divorced from his wife of 26 years Amy Van Nostrand in 2010.
