They've been friends for years, but only recently have things gotten romantical.
Not so, it seems.
Cuoco has just started seeing Arrow's Paul Blackthorne, 46.
Cuco and the dishy Brit attended WME's Golden Globes after party on January 10th at Chateau Marmont, according to Us Weekly.
"She’s been friends with Paul for years, but it’s recently turned romantic,” a source told the magazine.
“He is so handsome! She seems smitten. I think she’s a little cautious, but she seems really happy.
"They were longtime friends so there was already something there and they are seeing where it goes. He’s a nice guy.”
Over the weekend, Cuoco posed for photos the Art of Elysium gala in Culver City, as well as The Weinstein Company & Netflix's Golden Globe after parties, all solo. The star is trying to be as discreet about her new romance as possible.
Cuoco and Blackthorne have been reportedly dating since November.
“It’s new, but she’s really excited about it," a source told Us back in December.
So excited that she covered up her wedding tattoo with a giant moth, as you do.
