January Jones 'struggled to get X-Men body'

January Jones has said that it would have been impossible for her to portray X-Men: First Class character Emma Frost exactly as she is in the comic books.

Jones, who plays the narcissistic telepath in the Matthew Vaughn-directed film, revealed that she couldn't have attained Frost's flawless body in the amount of time that she had to prepare for the role.

"Emma Frost, my X-Men character, has an impossible body," Jones explained to the Daily Mail. "She has huge boobs with nice, womanly curves, but she is also ripped with muscle."

Jones went on to admit that her Mad Men schedule, in which she stars as '60s housewife Betty Draper, meant that she only had a matter of days before starting work on X-Men: First Class.

"In the amount of time I had to train, it just wasn't possible to achieve that amount of muscle without losing all the good bits," she continued. "We finished Mad Men at the end of August and I had one day to fly to London to start X-Men."

Jones recently announced that she was expecting her first child, but she has yet to reveal the identity of the unborn baby's father.

X-Men: First Class is due out in UK cinemas on June 1, and is released in the US two days later.
