New couple alert! Evan Rachel Wood is dating Ray Donovan actress Katherine Moennig, a source confirms to Us Weekly. And it all started after a couple of flirty tweets!

"Just saw @katemoennig at a flea market. I turned to mush and ran. Love her!!" Wood, who was married to Jamie Bell for two years, tweeted back in February 2013. "@evanrachelwood you should have said hi :)," Moennig replied.

Following their flirtatious exchange, Wood tweeted: "I had a dream @katemoennig and I were stuck in a cab together for hours during pride in NY. We just fell asleep though."

Wood, 27, who revealed she was bisexual after splitting from fiance Marilyn Manson in 2011, stuck by her new love's side at the Hammer Museum’s annual Gala in the Garden in Los Angeles on Oct. 13. According to Page Six, Wood and 36-year-old Moennig "were holding hands" and "kept close all night."

"Evan is crazy about Katherine. She had a crush on her for years but now can act on it," a source tells Us. "The age difference doesn't bother her at all either. She thinks they make an amazing couple. She is head over heels and Katherine feels the same way."

Wood split from Bell in May 2014 after nearly two years of marriage. The exes share a baby boy, whom they welcomed in July 2013. In a statement to Us, her rep said at the time: "Evan Rachel Wood and Jamie Bell have decided to separate. They both love and respect one another and will of course remain committed to co-parenting their son. This is a mutual decision and the two remain close friends."
