Braxton joined fellow artists Fergie, Nick Cannon, Celine Dion and 84 other celebs in autographing the gold bunnies, which fans and collectors can bid on throughout the month of April, with 100% of the proceeds going towards Autism Speaks, a charity close to Braxton's heart.
"As a mother of a son with autism, this is a cause that I am very passionate about," Braxton said in a statement. "I'm excited to be a part of the Lindt Gold Bunny Celebrity Auction, and honored to have the opportunity to help raise funds and awareness for Autism Speaks."
The 2011 Lindt Gold Bunny Auction is almost twice as big as last year's event, which included 59 gold bunnies and raised $10,000 for Autism Speaks.
