Bianca Wallace and Ioan Gruffudd looked smitten as they enjoyed the sights and sounds of London.
The Australian actress, 29, took to Instagram to post the sweet picture of her and the Welsh actor grinning for the camera as they posed by the river in the capital.
In the background is the London Eye, and Bianca rocked a black fedora, black winter coat and cream scarf as she posed while Ioan took the selfie.
The 48-year-old actor smiled while his girlfriend rested her hands on his shoulder, and he shielded his eyes from the springtime sunshine with a pair of designer sunglasses, teamed with a rugged leather jacket.
Bianca simply captioned the snap with a love heart emoji, and her followers were quick to heap praise on the new couple as they gave a rare insight into their relationship.
“I love this sooooo much! We've been waiting for a ‘couple’ photo!!!!,” one fan wrote.
“I don’t know you but well done for posting this picture and being brave,” another commented.
“Happiness is being with the one you love and trust!” one added.
“Oh man. This is so lovely to see. Lush,” a follower wrote, as another agreed: “Love this photo, radiating positive vibes, you are beautiful together. Bianca you look stunning.”
The couple went public with their romance seven months after Ioan filed for divorce from Alice Evans, the mother of his two daughters Ella, 12, and Elsie, eight.
The Hornblower star called time on their 21-year relationship in January 2021, and Alice took to Twitter to fire off a series of angry posts aimed at her estranged husband.
She has since accused Ioan and Bianca of conducting a three-year affair, which they have both denied, and alleged the actress contributed to the end of her marriage to the Welsh actor.
She claimed Ioan had begun his relationship while filming the TV series Harrow in Australia, on which Bianca worked as an extra.
Earlier this year, Alice launched into a furious tirade towards Bianca, as she slammed the actress for sharing a photo of her and Ioan holding hands on social media.
“She wants to put a stake in my heart. I've never seen such a lack of empathy. Pity, because we could have all been friends if they'd played this right. I have no problems with forgiveness. But this is evil,” Alice wrote.
