Port is fashion-forward in a floral frock and sandal-booties. Whitney tells us what she's looking forward to at the event: "I don't know what to expect. I heard it's fun. The ferris wheel looks fun. And hopefully some good food. I'm pretty hungry." She chatted with us about the prospect of her own MTV show. Get the scoop HERE.

New parents, Richie and Madden, work the Mattel station at the A Time for Heroes event. The sweet couple had a blast playing with children (and toys)! Later, they met up with gal-pal Mischa Barton, chatted, and posed for photos together.

Barton dresses up (sequin Chanel purse, Louboutin heels) for a day at the carnival. The starlet is put to work at the event, and giggles as she talks about her assignment: "I think I'm going to do more than one booth, hopefully. I think I'm starting over in the Barbie petting zoo. We'll see!" Read our Q&A with Ms. Mischa HERE.

A summer-ready Conrad works the "Biolage: Go Green, Grow Healthy" booth at the "A Time for Heroes" event with pals Whitney Port and Lo Bosworth. "I think it's a great charity. We all have very fortunate lives. It's nice we can spend the time here," Conrad tells us. Get L.C.'s summer fashion and beauty tips HERE.

Speidi arrive fashionably late for the event. The spunky twosome kept their distance from fellow event attendees Lauren Conrad, Whitney Port, and Lo Bosworth.

The quirky-cute couple attend the carnival event with their daughter Coco (who enjoyed the face-painting station and pixie-making booth). Courteney tells us why she loves to support the cause: "It's a great event. What they've done is amazing. You can see the money that's gone into this. It's put right to the cause. It's a really beautiful day in every way. People are sweet and fun. And it's so nice to see all the kids that have grown up." Read more of our interview with the duo HERE! David tells us about his Father's Day plans (or lack thereof)!

Richards is bronzed and beautiful in a white peasant-inspired ensemble. With her two adorable daughters in tow, Richards, who stars in her own reality show on E!, skipped the press line to go straight inside the carnival event. When asked if she'd stop for a quick interview, Richards laughed and simply replied, "Depends on who it's for!"
