Liza Weil dating 'How to Get Away with Murder' co-star Charlie Weber

June 8 (UPI) -- Liza Weil is dating her How to Get Away with Murder co-star.

The 40-year-old actress' representative confirmed to People that Weil has been seeing Charlie Weber since summer 2016.

Just Jared reported Weil and Weber "grew close" after splitting from their respective spouses, Paul Adelstein and Giselle Weber, in spring 2016.

"They have been dating under the radar for nearly a year," a source said.

Weil and Weber were first linked this week after they were spotted holding hands Tuesday in Los Angeles. The 38-year-old actor had dedicated a sweet message to Weil on her birthday the day prior.

"Happy Birthday to my beautiful and talented partner in crime..... @liza_weil," he tweeted Monday.

Weil and Weber play longtime co-workers Bonnie Winterbottom and Frank Delfino on How to Get Away with Murder. The characters shared a sex scene in Season 3 following the death of Bonnie's father.

"I think we get to see so many different colors of Bonnie and Frank," Weil told People after the episode aired in October. "There's a real vulnerability between them that we haven't seen before."

How to Get Away with Murder was renewed for a fourth season in February. The series is executive produced by Shonda Rhimes, and co-stars Viola Davis, Billy Brown, Jack Falahee, Aja Naomi King and Matt McGorry.
