Fans of the family series 7th Heaven may need a moment to process this—but little Ruthie is all grown up.
Actress Mackenzie Rosman proved to fans that she is no longer just a child star, but a sexy young woman with curves to flaunt, by posing in her undies for the September issue of Maxim.
"It must be Christmas, because we are delivering another brand new shoot with 7th Heaven's @Mack_Smack!" the mag tweeted.
Dressed in a pink lace bra and panties, Rosman gave a sweet over-the-shoulder smile at the camera while perfecting her booty tooch.
Another photo of the star was a bit sultrier, with the 23-year-old smizing at the camera as she laid on her back in the same negligee, along with a plaid top tied around her waist and a pair of sneakers.
This is definitely the first time fans have seen Mackenzie showing off her big-girl bod, but this is not the first time a lady from 7th Heaven has participated in a racy photo shoot.
Rosman's former costar Jessica Biel posed semi-nude for the cover of Gear magazine in 2000, which created a lot of buzz—both in Hollywood and on set of the show.
"I was probably nine at the time, but I remember that. It was a big deal," Rosman told the mag. "The magazine was banned on set, I think by orders of Aaron Spelling. I sneaked a peek at it, though. It was racy gossip amongst the women of 7th Heaven!"
Rosman is currently starring in the film Beneath and will appear in the TV movie Ghost Shark, premiering on SyFy Aug. 22.
