The 42-year-old American actress is famed for her trademark girl-next-door look. The star believes that, despite having a few laughter lines, her regular smiling is what makes her appear confident and beautiful.

You look most beautiful when you are happy. Ive got a few smile lines, but I dont worry about it. I love to smile! she told Glamour magazine.

The natural beauty always wows on the red carpet with her flawless skin and radiant complexion, which epitomises the California look. The star credits her healthy glow to the gorgeous weather and the sporty lifestyle she leads.

My health and happiness are down to the Californian sunshine. The weather and beaches make it easy to lead an active, outdoor life, she added.

Jennifers toned body is the envy of women across the globe. She insists that she is not excessive with exercise though.

I exercise regularly but not obsessively, she said. I do yoga three times a week. It calms and centres me. (C) Cover Media
