E!'s Bruna Nessif said the actress wanted to show the world her new self, "Actress Mackenzie Rosman proved to fans that she is no longer just a child star."

"But a sexy young woman with curves to flaunt," Nessif continued. "by posing in her undies for the September issue of Maxim."

Wearing only a pink lace bra and underwear, the former child star who played Ruthie Camden flashed an over-the-shoulder smile at the camera lens. 

In another shot, Rosman donned a strapless nude bra and underwear with what appears to be a chain-link top over it. She lifts up the top to expose her midriff, with her signature dark locks swept to one side.

With such racy shots that push the envelope, Rosman must have learned a trick or two from her former "7th Heaven" co-star and on-screen big sister, Jessica Biel. 

The "Playing for Keeps" actress had posed semi-nude for Gear magazine in 2000, shocking the world and many people including Rosman. The former child star recalled seeing the magazine, "I was probably nine at the time, but I remember that."

"The magazine was banned on set, I think by the orders of Aaron Spelling," Rosman continued. "I sneaked a peek at it, though. It was a racy gossip amongst the women of 7th Heaven!" 

Rosman is currently starring in the horror thriller, "Beneath"  and will have a role in the Syfy movie, "Ghost Shark" on Aug. 22.
