Jon Hamm reportedly wants to "settle down" with Dakota Johnson.
The former 'Mad Men' star has been "casually dating" the 'Fifty Shades of Grey' actress over the last few months and now the 46-year-old star - who has been single since splitting with long-term partner Jennifer Westfeldt in 2015 after 18 years together - is keen to take things to the next level.
A source said: "Jon thinks the world of Dakota and seems to be quite taken with her. He's been pursuing her and has been really enjoying her company.
"It's still early days but Jon has made it clear that he wants to settle down with someone soon.
"He has been actively looking for a girlfriend because he absolutely hates being single."
However, 28-year-old Dakota is said to be less certain of the future than Jon - who has also been romantically linked with Juno Temple, Jenny Slate and Kate Beckinsale since splitting from Jennifer - and wants to keep things casual for now.
The source told Grazia magazine: "She's enjoying their dates, but she's told friends she's just not sure he'd be the right person to settle down with and she's aware that that's what he wants. He's very keen but she's taking her time."
And it seems the brunette beauty is keeping her options open, as she was recently spotted on a dinner date in Los Angeles with Coldplay frontman Chris Martin.
The pair were said to be "cozy, laughing and affectionate" during their intimate meal at a sushi restaurant.
Dakota previously enjoyed a lengthy on/off relationship with model-and-rocker Matthew Hitt, but it's believed they called time on their romance some time last year.
Jon and Dakota were first pictured together at Sir Elton John's 70th birthday party in March and have since enjoyed a string of meetings, most recently at Kingside restaurant and bar in the Viceroy Central Park Hotel in New York.
