Kevin Jonas: Jamba Juice Jabber

Kevin Jonas walks back and forth as he chats on his cell phone in front of the Casa del Mar hotel in Santa Monica on Tuesday (May 10).

While the 23-year-old musician, he cooled down with a Jamba Juice smoothie. Yummy!

Over the weekend Kevin stepped out at the City of Hope event honoring Shelli and Irving Azoff with the 2011 Spirit Of Life Award.

Psst, have you bid on a chance to get a phone call from his brother Joe yet? Last day is tomorrow!
