Joe Jonas knows when you’re as hot as Gigi Hadid you’re not single for long … which would be a great reason for him to be so close to her in some newly released pics of the pair. However, it might not be what it seems. Newly single Gigi, who just broke up with Cody Simpson — was spotted hanging out with Joe in L.A. on Wednesday … and cruising puppies in the window of a pet store. Normally, shopping for a joint pet is a sure sign of coupledom, but a source close to Joe and Gigi tells TMZ they’re just longtime friends. Sadly, no puppies were also reportedly purchased.
