LeAnn Rimes took a break from her month long birthday celebrations Saturday, swapping her skimpy bikinis for a white dress and performing at the 17th Annual Symphony at the Salk Institute in San Diego, and Breaking Celebrity News has the photos.

The country star performed with the San Diego Symphony and guest conductor Thomas Wilkins at the fundraiser which supports the biological research at the Salk Institute and its community education programs.

As Breaking Celebrity News previously reported, LeAnn, who turns 30 on Tuesday, has been enjoying weeks of birthday celebrations.

She kicked off the festivities with a bikini party two weeks ago in Malibu, packing on the PDA with hunky hubby Eddie Cibrian.

Then on Tuesday LeAnn tweeted a pic showing her wearing a teeny-weeny white string bikini while standing alongside bottles of booze.

“HUGE thx to @donjulio for providing the tequila and mixologist for my 30th bday!!!” she wrote.
