Model/singer Pixie Geldof has cancelled a planned Dj performance at the Coachella music festival in California this weekend (12-13Apr14) following the death of her sister Peaches.

Pixie has yet to break her silence about the sad loss, but she has pulled out of a Coachella gig on Saturday (12Apr14) to mourn Peaches' sudden passing.

An event spokesperson says, "We can confirm that Pixie Geldof was scheduled to Dj at The Old Navy Oasis event, but is no longer participating."

Peaches Geldof was found dead at her home in Kent, England on Monday (07Apr14) and initial autopsy results have proved inconclusive. A cause of death is not expected to be determined for several weeks until toxicology results are made available.

The late socialite's father, rocker and Live Aid legend Bob Geldof, led the tributes to the 25 year old after confirming her death on Monday, and her eldest sister, Fifi, remembered Peaches in an emotional post on Tuesday (08Apr14).
