Sharon Stone is ''enjoying'' the ageing process.

The 55-year-old actress claims there is no secret to her slender figure and insists her youthful looks are down to being ''happy''.

Sharon told E! News: ''I think I am ageing but I'm enjoying the process. I think that's really it. I'm enjoying my years, I'm enjoying my life, I'm enjoying my family. I'm just happy ... a happy person.''

The 'Lovelace' actress previously insisted she's had no secret plastic surgery and instead opts for a healthy lifestyle to avoid going under the knife.

She said: ''My secret is no secret, I just do all the things you're supposed to do. I eat right, I sleep, I work out, I'm happy. I have a beautiful family, nice friends. I choose the good things. I choose the happy, healthy things. I don't choose the bad, unhealthy, unhappy things.''

The star admitted last month that she has resisted a facelift, despite constant offers from plastic surgeons.

She revealed: ''I can't tell you how many doctors try to sell me a facelift. I've even gone as far as having someone talk me into it, but when I went over and looked at pictures of myself, I thought, what are they going to lift?''
