Emily VanCamp has recently gone public with her romance with co-star Josh Bowman because "they don't see it ending."
The pair star as lovers in hit television series Revenge and their on-screen romance has spilled over off screen.
The 25-year-old actress and the British star, 24, started dating around three months ago and have been seen out in public being affectionate with each other recently.
"They tried to have a secret relationship at first," a source told Us Weekly. "But now they're not worried because they don't' see it ending."
"It still feels sweet and new to them. They hang out together every night. They can't keep their hands off each other."
Emily has reportedly dated her Brothers & Sisters costar Dave Annable in the past and dealt with breakups with ex-boyfriends Chris Pratt and The Vampire Diaries' star Joseph Morgan.
Emily and Josh are said to have got together after seeing in 2012 with friends at Paris club Rasputin.
