The 38-year-old actress made comments about a former boyfriend who "wasn't encouraging" during an interview in 2009, and has now denied claims she was talking about former flame and fellow actor Ashton Kutcher.

She said: "I said that someone I had dated previously wasn't encouraging of my acting. Not that I couldn't. I don't know if that person had ever actually seen me act."

The 'Mad Men' star claims that the interviewer at the time reached the conclusion that she must have been talking about the 38-year-old hunk, but insists she never gave any names.

Speaking on US TV show 'Watch What Happens Live', she said: "The person who wrote the interview did the math and thought it might be him. I never really said who it was."

When pressed on the show as to whether or not she was speaking about the 'Jobs' actor - who is now married to actress Mila Kunis - January merely smiled and refused to comment.

However, the 'American Wedding' actress - who has five year old son Xander - did have some kind words for Ashton as she said she was "super happy" that him and Mila, 33, are expecting their second child together.

She said: "I haven't talked to him, but I'm super happy for him and his family. To be political and all that."

As for budding romance in January's life, it was reported in April that she was starting a relationship with 'The Last Men on Earth' co-star Will Forte.

An insider said at the time: "It's very new. They're seeing where things go. He's a good guy."
