January Jones is dating director Noah Miller.
The 'Mad Men' star - who has an 11-month-old son, Xander - has been spotted out with the film maker on several occasions after meeting on the set of their new film, 'Sweetwater'.
A source told Life & Style magazine: ''They met on the set of the film 'Sweetwater'. January's one of the stars, and Noah's co-directing with his twin brother, Logan.''
It is thought Noah is the first person January has dated since welcoming Xander into the world last September.
She has refused to say who Xander's father is and vowed to raise him as a single mother.
She recently admitted being a working mother was hard and said she was fortunate she could take her son to work with him when she returned to the set of 'Mad Men'.
She said: ''I had to go back to work when Xander was six or seven weeks old, but I'm lucky that I have a job that I can bring him with me. I was able to bring him to work and nurse, and I could see him when I missed him, which was often even though I was only feet away.
'''Mad Men' has such long hours, and then you go home and you don't sleep. So it was hard.''
