Sheryl Crow, 51, shows off her toned figure in a rippling dress at a charity event to save the oceans

Sheryl Crow not only puts her money where her mouth is, she also sings to support a cause she believes in.

The country star performed at a private concert on Sunday in Laguna Beach, California, to raise money at the Oceana SeaChange Summer Party.

The fabulously fit 51-year-old was suitably dressed in a grey and white layered dress that rippled over her like a cool wave of water.

Crow paired the beautiful outfit with steel grey and silver paneled shoes and carried a grey wrap to keep her warm once the sun set.

The breast cancer survivor showed off her incredibly toned and tanned figure that makes her look far younger than her years.

Sheryl does Beachbody trainer Tony Horton's P90X workout DVDs at home, which focus on 'muscle confusion' to keep your body constantly challenged and induce change.

'I take workouts with me on tour: P90X, Tracy Anderson. I do them in the hotel rooms,' revealed the 100 Miles From Memphis singer to Self Magazine.

'I'm not big about going to gyms. I've been known to workout out on a treadmill or StairMaster, but my first choice is really getting outside and running. That's where I can really clear my head.'

As for her famously sculpted in arms that she showed off in the capped sleeved dress on Sunday, Sheryl has previously claimed that they are a result of good genes - and motherhood.

'I have to be honest with you, I come by them naturally,' said Lance Armstrong's ex-girlfriend, who has two adopted sons, Wyatt and Levi. 'I lift a 3-year-old throughout the day; I'm sure that has something to do with it.'

All those workouts no doubt meant that the C'mon C'mon singer could enjoy the gourmet sit down dinner at the Oceana gala held at a private estate called Villa di Sogni, before hosting the live auction.

The exclusive charity event raised money to fund the largest international organization focused on the ocean conservation.

'We believe in the importance of science in identifying problems and solutions,' explains the Oceana website Our scientists work closely with our teams of economists, lawyers and advocates to achieve tangible results for the oceans.'

Some of their biggest victories have included an EU ban on shark finning, halting offshore drilling in Belize, reforms for Europe's fisheries and protection of Great White sharks in California.

Crow was joined at the exclusive evening by a celebrity friends including Anne Heche, who wore a classic dusky pink dress with a zippered neck detail.

Cheers star Ted Danson was there with his actress wife, Mary Steenburgen, in a pink and navy blue ensemble.

Miley Cyrus' Hannah Montana co-star, Emily Osment was also in attendance. The 21-year-old singer/actress - whose brother is Sixth Sense star Haley Joel Osment - wore a nautical theme sailor jacket over a white dress with red sandals.
