January Jones doesn't "like living with other people".

The 'Mad Men' beauty split from her boyfriend of nearly a year Jason Sudeikis at the beginning of the year, and she claims she is happy living the single life and is disillusioned with relationships which go nowhere.

She told Marie Claire magazine: "I don't like living with other people. I don't mind being alone. I just don't really have a lot of time or energy to put into a relationship when nothing's going to happen."

The 33-year-old star - who plays Betty Draper in the TV series -added: "Everybody writes that they think I'm so unhappy. I'm [just] in my own head. I'm doing things. Keeping things interesting.

"I don't like having an entourage of people around me. I have a select group of friends who I hang out with."

January is enjoying her sex symbol status as it has allowed her to get her own back on the people who were mean to her when she was in high school.

She added: "The bitches in high school were bitches because I was pretty."

But January, who is also set to star in forthcoming superhero film 'X Men: First Class', refuses to change herself or her opinions to make people like her, adding: "I don't have to sell myself to make myself more likeable.

"When I'm talking about myself, half the time I'm lying. I do it because I'm bored of talking about myself, or I have nothing left to say, or I want to be private that day."

Speaking of the way her career has soared since she landed the role of Betty in 'Mad Men' in 2007, January admitted she was initially hesitant to accept it.

She said: "I'd done films, but never TV. I was hesitant because it was a five-year contract and there wasn't really a role for Betty in the pilot. I think this is a really good moment for me.

"Nothing ever came to me too easily or too fast, so I've been able to adjust. I've never got too bitter or jaded."
