The Pratts' longtime friend, and professional surfer, Lexi Vonderlieth will ride some waves for the cause ... even giving Heidi personal surf lessons. "You'd be surprised at how good Heidi is on the board," Lexi tells X17online.

Sources close to the couple tell X17online exclusively, "Heidi has been taking time away from her busy schedule to prepare for these fundraisers. They want to have it this August. Spencer plans on shooting both events for a 30 minute documentary with all the money raised going for the cause."
