She was more than happy to support a really great cause.

Camilla Belle was among a host of celebs who flocked to L.A. Loves Alex's Lemonade event — which raises funds to fight childhood cancer — on a sunny afternoon at UCLA's Royce Quad on Saturday in Los Angeles.

The 32-year-old actress kept cool in a sheer, ankle-length purple dress with a pale pink pattern that she cinched at the waist with a wide silver belt.

The beautiful brunette smoothed her tresses back into a low pony tail and sensibly wore white sneakers rather than risk getting her high heels stuck in the quad's lawn.

She posted in Instagram snap of herself enjoying an ice cream, captioned: 'Another incredible year raising awareness and funds for children's cancer research at @lalovesalexs . A smashing success. ' 

Others at the garden party included actress Laura Dern, 52, and her daughter Jaya Harper, 14. 

Laura also opted for sneakers and matched a white T-shirt with a grey plaid jacket, black skinny jeans and a white handbag.
