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

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.
