Baby and a bob! Single mom Malin Akerman showed off her new haircut while taking a walk Friday, Feb. 21 with her adorable 10-month-old son Sebastian.

Revealing significantly shorter blonde locks, the Trophy Wife star looked casual and chic in black leggings, a graphic T-shirt and oversized sweater as she coddled her little one outdoors. Her haircut, however, is several weeks old!

An insider at the ABC series' wrap party in Burbank on Feb. 9 told Us the blonde star's new look was "really cute" and that she got it "as soon as the show wrapped." The following day, Akerman's onscreen stepdaughter Bailee Madison notified reporters during a panel of the star's new look: "Malin cut her hair, everybody," the 14-year-old stated.

"That's news!" Akerman sarcastically joked. "Thanks, Bailee."

Along with her hair, the suddenly-single Swedish-Canadian actress has endured many changes within the last four months. As previously reported, Akerman and rocker Roberto Zincone split in November after six years of marriage. He filed for divorce just seven months after little Sebastian, the couple's only child, was born. But Akerman seemed happier than ever when she spoke with Us in January about Sebastian's latest milestones.

"It's so much fun. I mean, every moment," she gushed of life with her baby. "I get to bring him to work every day… he comes down to set. Everyone on set are like his aunts and uncles."
