The ultimate '90s reunion is set to take place on Grandfathered!

Drake Bell will appear alongside his Drake & Josh co-star Josh Peck in a spring episode of the Fox comedy, as confirmed, and he'll be playing the polar opposite of his lazy, scheming Nickelodeon character.

As ET first reported, Bell will be guest-starring as Kirk, a snazzy tech investor whom Gerald (Peck) and Vanessa (Christina Milian) are desperate to pitch their new app to. Unfortunately, things don't quite work out. When they finally meet with the young entrepreneur, they start to wonder if he's really the best person to be in business with.

Peck and Bell co-starred on Drake & Josh from 2004 to 2007 and appeared in two TV movies for the series.

Grandfathered airs Tuesdays at 8/7c on Fox.
