Jenny McCarthy swears by Botox.

The 39-year-old TV presenter has admitted her youthful looks aren't completely natural but insisted she is careful about the amount of work she has done.

She told Life & Style magazine: ''I'm an obvious Botox user. I tell everyone.

''I get Botox in my forehead. I just have my doctor do a little shot.''

However, Jenny does have another reason for looking so good.

She explained ''Having your sister be your professional make-up artist helps. I just kind of take care of myself.''

The 'Love in the Wild' host's beauty methods are obviously working as she recently bagged herself a new man, NFL player Brian Urlacher, but Jenny - who has a nine-year-old son Evan - is being cautious of how things develop.

She previously said: ''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.''

''I have a six-month rule. I don't introduce my son to anybody unless someone makes it six months.''

Jenny split from husband John Mallory Asher in 2005 and dated Jim Carrey for five years until 2010.
