Desperate Housewives' Marcia Cross is wrinkle-free and glowing at 47

With glowing, line-free skin, Marcia CrossMarcia Cross could pass for a woman 20 years her junior.

The 47-year-old is a walking advert for whichever skin cream she uses - if that is the secret behind her youthful skin tone.

It is even more surprising that she looks so fresh-faced with two-year-old twin daughters Eden and Savannah to run around after.

The Desperate Housewives actress, who plays Bree in the sitcom, has also had a tough year after her husband Tom Mahoney was diagnosed with cancer in January, so she could be forgiven for having plenty of worry lines.

But Marica looked happy, positive and wrinkle-free as she was photographed at the Rock A Little, Feed A Lot benefit concert in Los Angeles yesterday.

Dressed in a glittering sleeveless top with a scarf neckline and shiny, tight black jeans and black nail polish, the slender actress pulled off a youthful rock chic look.

With the same colouring as actress Nicole KidmanNicole Kidman, perhaps she keeps a similar beauty regime to the Hollywood icon.

Despite persistent rumours that the 41-year-old has resorted to Botox, Nicole denies this and puts her youthful looks down to staying out of the sun and 'drinking lots of water, eating fruit and doing yoga'.

According to Us Weekly, Marcia uses the super-hydrating celebrity favourite Creme de la Mer.

Last year Torchwood star John Barrowman said he thought women who had succumbed to botox looked great.

The gay actor told Closer magazine: 'This is going to sound really camp, But I love women who are Botoxed to the nines. Bree on Desperate Housewives is incredible!'

Marcia was one of the presenters at the Rock A Little, Feed A Lot concert, along with stars such as Friends actresses Lisa KudrowLisa Kudrow and Courteney CoxCourteney Cox Arquette, Christina ApplegateChristina Applegate and Isla FisherIsla Fisher.

Kudrow had taken to the stage to introduce singer Sheryl Crow only to find herself with a guitar thrust upon her.

After the audience called out for her to play, she looked to her former co-star for help but Cox Arquette gleefully called out to the stagehands: 'Get her a guitar, people!'

After being given an acoustic guitar, the actress warily asked, 'Is this a set up?'

The concert raised funds for charities Feeding America, the country's largest domestic hunger-relief charity, and the Los Angeles Regional Food Bank.

The last song of the night was written for the night, and called 'All We Need Is Love', which is being released as a single next week.
