January Jones is dating Nick Viall.

The 'Mad Men' actress is reportedly in a relationship with 'The Bachelor' star after the pair hit it off after meeting on 'The Late Late Show with James Corden' last year.

A source told the New York Post's Page Six column: ''They've been dating for about two months. She went on 'The Late Show' in ­mid-November and said Nick had reached out to her and tried to get her to lip-sync battle with him. She declined, but then he asked her out to a drink and she accepted. They've been seeing each other since.''

Meanwhile, January previously confessed she is on the look out for ''dirty'' younger men.

She said: ''The moment I see someone I think is cute, I Google him and oh, he's 25, and I'm thinking, 'What's my problem?' My sister too. She lives in Los Angeles and we both like tattoos, guitar, kinda dirty ...

''Is the sex great though? Do they know what they are doing? I guess you can teach them. But I want a manly man in flannel with a beard and an axe. But there's always something wrong. Like, he's a Republican.''

January's friends have been keen to set her up on dates but she insists she isn't interested.

She added: ''People want to set me up all the time and I'm like, 'No way.' If I meet someone and we go out, fine, but I'm not going to look ... I'm willing to make that sacrifice for the right relationship - I just don't feel I need a partner. Do I want one? Maybe. But I don't feel unhappy or lonely.

''It would have to be someone so amazing that I would want to make room. Someone who would contribute to my happiness and not take away from it. After I had Xander, I went on a couple of dates and I was like, 'I'd rather be at home sleeping, watching TV, or hanging out with my kid.''
