The singer may have wanted to run through the halls of his Connecticut high school and scream at the top of his lungs, but he was quite the conservative little guy here, wearing his dress shirt and tie, in his early school days. “#tbt this guy,” Mayer captioned this shot. Fun fact: We want to pinch this guy‘s cheeks. (Photo: John Mayer via Instagram)

Reliving the awkward phase glory days! As the remaining schoolkids headed back this week (how cute are J.Lo’s, Jessica Simpson’s, and Jessica Alba’s wee ones?!), we’ve seen our fair share of first-day photos. Now it seems older stars want in on the action by posting throwbacks of their school days. See John Mayer looking like a little businessman, Dax Shepard rocking some OP, and more gems.
