Jamie Lee Curtis advertises Activia

Here's Jamie Lee Curtis in her latest role - advertising yoghurts on US television commercials.

The Trading Places star is the new face of food giant Dannon and will appear in a series of adverts promoting the company's Activia products.

Dannon claims the probiotic yoghurt-like drink aids digestive problems.

Curtis said in a statement: "Digestive problems are important and surprisingly common but we don't discuss them.

"Whereas we routinely talk about other uncomfortable topics, such as erectile dysfunction, digestive health is not being addressed - and it's time to change that.

"I am not afraid to talk about bowel issues - there I said it - and I'm very committed to help people find solutions, like a balanced diet and Activia.

"It is rewarding to be the ice breaker who speaks openly about digestive health and irregularity, and make it easier for people to find a solution."

Curtis, 49, will next be seen on screen in Disney live-action comedy, Beverly Hills Chihuahua.
