Is there a proper time that defines whether a photo is eligible for Throwback Thursdays? This week, celebrity throwback photos are from the ’90s, up to a few months ago. While Elle Varner and Christina Milian took us back to their childhoods, Kandi Burruss takes us to the good old days before reality TV. Kim Kardashian and Diddy show off throwback photos that look like they were taken just weeks ago — is that really throwback? While you decide, take a look at these celebrities and more who posted their throwback photos on Instagram this week.
