After a rough few months following the end of her marriage to Ashton Kutcher, the 49-year-old actress attended a soiree in Beverly Hills to support her best friend Amanda de Cadenet.

Last year the star’s weight plummeted and she looked gaunt as she stepped out to the premiere of her movie Margin Call in New York in October.

But last night the Ghost star – who executive produces her pal de Cadenet’s TV show The Conversation – appeared to have put on some weight.

De Cadenet spoke about the upcoming show, where she interviews big Hollywood female names about womanhood.

She said: “I’d been doing these interviews for about a year and Demi is one of my best girlfriends and a great sounding board for me.

“She’s got 10 years on me, and so she is more ahead of me in the game of being a woman. She is an amazing resource for me, and so she has a vast life experience that I love to experience and to hear.”

Moore was rushed to hospital on January 23, when she started convulsing after doing nitrous oxide at home with friends, according to US reports.

The star revealed the day before that she was ready to change her Twitter name from @mrskutcher.

“Time for a change, twitter name change… any suggestions?” she posted.

Kutcher has been linked to Rihanna and Lorene Scafaria in recent weeks and was spotted in the company of a mystery blonde in the last week.
