Hayden Panettiere showed off her post-baby weight while shooting in New YOrk for her new movie, "Custody."

"Wearing skin tight purple leggings, a grey marl V-neck tee shirt and a hooded denim jacket the pretty star hot-footed it across the set in bright pink trainers," said Daily Mail.

"With her skin as glowing as ever, the youthful beauty looked barely a day older than her teens, with minimal make-up and jewellery as she readied herself to take on her latest acting role," it added.

The British tabloid also took note of the "figure-hugging ensemble" that Hayden Panettiere wore, which only proved that she's losing her post-baby weight.

Hayden Panettiere and partner Wladimir Klitschko welcomed baby Kaya on Dec. 9 and the "Nashville" star announced that she's makig it her New Year's resolution to drop the post-baby weight.

"Hayden was on-set preparing for her next film, Custody, which will also star actress Viola Davis follows three women whose lives unexpectedly intersect at a New York Family Co," the article added.

"Hayden is impatient about losing the pounds-and eager to have her figure back before awards season-he's not letting her go to extreme measures to get back in Hollywood shape," said OK! magazine.

Wladimir Klitschko told Hayden Panettiere to "take her time" and start trying to lose the baby weight in February instead.

"As a world heavyweight champion, Wlad is serving as Hayden's coach to ensure she gets in tip-top shape the correct way," the article added.

Hayden Panettiere couldn't help but gush about baby Kaya in an interview with Good Morning America.

"It's fabulous every day," she said. "You hear that the [baby is] healthy and you don't care about yourself anymore. I mean it's the most out-of-body experience where you go, 'I will completely lay myself on the line for my child without even a hesitation.'
