Ever heard of a belfie? Well, not to tell tales out of school, but it’s the butt version of a selfie. And as Kelly Ripa recently discovered, you should really be careful who you send one to.

On Wednesday’s Late Show With David Letterman, the Live co-host fessed up to a rather cringeworthy moment: she accidentally sent a belfie to her husband’s parents. (Its intended target: her hubby, naturally.)

Fortunately, Kelly’s mother- and father-in-law weren’t overly fazed by the sexy posterior pic. In fact, they simply replied with an e-mail that read, “We’re so proud of all the hard work. Your exercise classes are really paying off.”;

Just to show she hasn’t learned her lesson, Kelly took another belfie backstage at Late Show and posted it to Instagram. And we have to agree with her in-laws: those classes really are paying off!
