Tom Hiddleston And Elizabeth Olsen's romance have been circulating the rumor mill since May.
Speculations escalated further when they were spotted going out for dinner together in London last August.
Now that promotions for "I Saw The Light" has started, will they be showing off their alleged romantic connection in front of the cameras?
While they looked cosy in each other's arms as they hung out around London some weeks ago, Tom Hiddleston and Elizabeth Olsen seemed to have kept their rumored romance on the down-low, keeping things professional, during the red carpet event of the Toronto International Film Fest earlier this week.
Starring as Audrey Williams, Mary Kate and Ashley's younger sister posed for photos at the red carpet event alongside her co-star and rumored beau who plays her onscreen husband, Hank Williams.
According to The Daily Mail, the 26-year-old caught everyone's attention when she arrived in a "dramatic black gown that had a peplum top and sleeves." Meanwhile, the "Avengers" star looked debonair in a navy blue suit.
The speculated couple reportedly started seeing each other casually in May but still made sure "to text when they're apart."
Olsen later "went to meet up with Tom after doing Paris Fashion Week and wrapping on 'Captain America: Civil War,'" which was when they were spotted out and about in London for a couple of days together.
Despite being seen in public together multiple times already, neither Tom Hiddleston nor Elizabeth Olsen have admitted to their budding romance publicly. Not even when they started promoting "I Saw The Light" at TIFF earlier this week.
Meanwhile, the "Crimson Peak" actor shared a sneak peek of his new film with his rumored girlfriend on Twitter earlier this week. The clip shows him as Hank Williams singing "Move It On Over."
