Jimmy Kimmel's adorable baby boy Billy looked happy and content on Saturday when the whole family turned out for the 8th Annual L.A. Loves Alex's Lemonade event at UCLA's Royce Quad.
Kimmel, 49, held his sleeping infant son in his arms and out of the sun as he, his wife and his daughter smiled for photos outside the event, which benefitted the Alex's Lemonade Stand Foundation for Childhood Cancer.
ET caught up with Kimmel and his adorable daughter at the Fifth Annual Ping Pong 4 Purpose Celebrity Tournament at Dodger Stadium in July, where he shared his appreciation for those who supported his family during that difficult time.
"We're very grateful for everyone's kindness," Kimmel said. "He's doing really great and we're all very happy about that." Check out the video below to hear more.
