The beautiful actress looked sensational in a floral patterned yellow dress while walking the red carpet with Richard in Los Angeles on Sunday evening (1 March).
Handsome Richard – known to many as Robb Stark in Game of Thrones - plays Prince Charming in the new live-action version of the classic Cinderella fairytale.
Lucky Jenna is all we can say!
The couple were joined on the Hollywood red carpet by Richard's co-star, Downton Abbey actress Lily James, who plays the titular Ella.
Speaking with ELLE about his role, Richard said recently: "I tried to take all the stigma away from Prince Charming and just go into the story, which is about two young people with a lot on their plates.
"He's not just sweeping in on his horse and saving the damsel in distress. This is a real man dealing with real issues. You get to see that, I think."
Cinderella, directed by Sir Kenneth Brannagh, arrives in cinemas on 27 March.
