Gavin Rossdale: Killer Abs in Cannes!

Gavin Rossdale shows off his killer abs while hanging out shirtless at the Hotel du Cap Eden Roc on Wednesday (May 18) in Cap d’Antibes, France.

The 45-year-old rocker, who was joined by his sons Kingston and Zuma, hopped aboard a boat and took a swim with the boys.

Gavin is in France for the 2011 Cannes Film Festival, during which he attended the premiere of The Tree of Life with his wife Gwen Stefani earlier in the week.
