Pregnant Reese Witherspoon at Kidstock 2012 Pictures

Reese Witherspoon capped off a busy weekend yesterday at LA's sixth annual Kidstock Music and Arts festival. The event, which raised over $300,000 for One Voice organization, brought out major names like Victoria Beckham, Scott Foley, Greg Kinnear, and Pete Wentz. Pete was joined by girlfriend, Meagan Camper, and son, Bronx. The trio were spotted customizing a pair of toddler-sized Hudson jeans for Bronx. Reese helped Ava and Deacon Phillippe create their own designs as well, with Ava picking out a rainbow and heart patch for a purple pair of skinny jeans.

In addition to arts and crafts, the Drybar salon was also styling hair for the little ones. Ava left with pink streaks and glitter highlights while the Beckham boys, Romeo, Brooklyn, and Cruz opted for mohawks. The Beckhams had an exciting weekend on the West Coast and across the pond. David was in London to accept a special soccer honor while Victoria went shopping with the kids and kept a close eye on the fashion happening at the Queen's Diamond Jubilee.
