Well, this is quite a striking pair!

Your boyfriend Tom Hiddleston and Elizabeth Olsen attended the premiere I Saw the Light at the 2015 Toronto International Film Festival on Friday, months after they sparked romance rumors. Hiddleston, 34, plays singer-songwriter Hank Williams in the film, while the 26-year-old actress portrays his wife, Audrey Mae Williams.

The younger sister of 29-year-old twins Mary-Kate Olsen and Ashley Olsen and the actor, who play Loki and The Scarlet Witch in The Avengers franchise, have not confirmed a relationship. They first sparked dating rumors in May and were last photographed together in late July, sharing a taxi after sharing a taxi cab after having dinner at a restaurant in the actor's native London.

At the I Saw the Light premiere, the two walked the red carpet and posed for photos together, with Hiddleston's arm around Olsen's waist. She wore a black silk gown with a peplum waist and matching sleeves and an asymmetrical tulip skirt. The actor looked dapper in a navy suit, pale blue shirt and dark blue tie.

They also attended the event's after party together, acting goofy and adorable together while admiring a special movie-themed cake.
