January suits us year-round: January Jones [SLIDESHOW]

Laura Donovan Contributor

Don’t let her first name fool you. According to fellow “Mad Men” cast member John Slattery, actress January Jones is “a sweetheart” and nothing like her chilly, on-screen character Betty Draper.

In a recent interview with E!, Slattery spoke highly of the Sioux Falls, South Dakota native, who announced her pregnancy in April.

“[S]he’s a sweetheart,” Slattery told E! of Jones, adding that the 33-year-old is no diva. “We got lucky.”

With a baby on the way, Jones could get away with high maintenance demands, but the television star keeps it real. Scroll through our slideshow below for pictures of the down-to-earth blonde and future mom.
