CNN's Piers Morgan let one romantic cat out of the bag. After rumors swirled for months, the Brit confirmed in a blog post that Charlize Theron and Sean Penn are dating.

Morgan recounts in his Mail Online blog about going to an auction event hosted by his friend Penn. While there, he saw Penn and his "new girlfriend" Theron sitting together.

"I'm so glad you two have got together. Sean's a great guy," Morgan recalls telling Theron. Her response: "I know."

Among the items being auctioned off was a Jeff Koons creation made of 67 of Penn's firearms melted down. Anderson Cooper won it with a $1.4 million bid, but not before Morgan offered $1.3 million.

Penn credited his decision to get rid of his weapons to Theron. "I'm a self-proclaimed Alpha male who owns 67 firearms. But I've had my mind changed about guns by a strong woman, a beautiful South African woman," he reportedly said, bringing Theron close to tears. "I don't need these cowardly instruments of violence and destruction, none of us do."

Before leaving, Morgan writes that Penn told him of Theron: "She's a keeper, that's for sure ... well, I'll do my best to keep her anyway!"

Are you surprised Penn and Theron are actually a couple?
