Jenny McCarthy credits Botox for her youthful look

London -  Jenny McCarthy has revealed that the secret to her youthful looks is a healthy supply of Botox.

The 39-year-old TV presenter said that she recommends the treatment to all her friends, but added she is careful not to use too much.

“I’m an obvious Botox user. I tell everyone,” the Daily Mail quoted her as telling Life ‘n’ Style magazine.

“I get Botox in my forehead. I just have my doctor do a little shot,” she said.

The classy model, who started her career by baring all for Playboy, also said she has another secret weapon in her beauty armoury.

“Having your sister be your professional make-up artist helps,” she explained.

“I just kind of take care of myself,” she said.

She recently hooked up with NFL player Brian Urlacher, but she said she is being cautious of how things develop with the Chicago Bear.

“I haven’t made too many comments other than the fact that I’m taking baby steps. We’ll see. But I’m giddy right now,” she said.

“I have a six-month rule. I don’t introduce my son to anybody unless someone makes it six months,” she revealed.

Since splitting from John Mallory Asher in 2005 she has had an active love live, even having a tryst with porn star Jenna Jameson, and dated The Mask star Jim for five years until 2010.
