Kaley Cuoco could have a new man in her life after splitting with her husband of almost two years, Ryan Sweeting, in September.

The 30-year-old Big Bang Theory actress is dating 46-year-old Arrow star Paul Blackthorne, Us Weeklyreports. "It's new, but she's really excited about it," an insider tells the magazine.

Reps for both Cuoco and Blackthorne declined to comment.

We do know that Cuoco and Blackthorne are at least good friends, as Cuoco Instagrammed a picture of herself supporting Blackthorne's conservation charity for wild elephants last month.

"Help my friend @paulblackthorne @airshepherd #KeepRhinosHorny," she wrote, proudly sporting his T-shirt.

Blackthorne also re-posted Cuoco's pic on his own Instagram, offering a chance for those buying the T-shirt to win one signed by Cuoco.

So what do we know about Cuoco's possible new man? Blackthorne is a British actor as well as an accomplished photographer, and has had roles on ER, 24, and Lipstick Jungle. He currently plays Detective Quentin Lance on Arrow. A source tells ET he was engaged a couple years ago, to a woman who is not a celebrity. He also dated Daryl Hannah in 2010.

Cuoco and Blackthorne also share the same agent, and aside from their television background, have a common passion for animals. Blackthorne's Instagram is filled with posts on his conservation efforts, including this pic of him sporting his own face on a T-shirt, reading, "Poach eggs, not elephants."

Last month, Cuoco hosted the All-Star Dog Rescue Celebration, and has made her love for animals -- specifically her six horses -- well-known.

"I ride horses five days a week whenever I can," she told Shape in September. "I have six horses, and they have been the biggest blessing in my life. Horseback riding is why I'm so centered, especially in this business. I wouldn't have my career without it."
