Since appearing on the cover of our Summer Music Issue this year, Joe Jonas has been busy promoting his dance-y new solo album, Fastlife. Recently, he toured with Britney Spears through out Europe, supporting the pop princess on her Femme Fatal tour (and getting a much-buzzed-about lap dance from Spears during their show at Wembley Arena last week. Wowee.). We asked Joe to keep a photo diary for us during the final days of the tour and here's what he sent over. Good to know the Jo Bros still pick each other up from the airport!
