Pop star Katy Perry ended her relationship with John Mayer a long time ago, but it looks like the "Daughters" star may have changed his body image ever since the split.

On Friday, Daily Mail posted photos of the singer as he arrived at LAX in a striped shirt, black jacket and jeans. As he added on a pair of sunglasses and brown shoes, Mayer looked like he lost some weight lately. His figure looked pretty thin, giving some insight on why that could be. Some might assume it's because he's not eating lately or trying to hurt himself due to the breakup with Perry. But it might be too soon to jump to that theory right now.

His new figure could have nothing to do with his ex-girlfriend, but maybe because he might not be working out that much.

It doesn't look like Mayer is currently seeing anyone else right now although his ex-girlfriend might be. Rumor has it that Perry could be dating DJ Diplo ever since they were spotted together at Seth Meyer's Emmy party. According to an insider from Perez Hilton, the two were having some flirty moments that were pretty public.

"[They] kept grabbing each other's hands and Diplo kept pulling Katy in," the source said.

This might cause some to wonder how Mayer feels about this; if Perry really is dating Diplo, then the "No Such Thing" star might be having a hard time dealing with it.
