Former child Rap duo Kriss Kross is back – at least long enough to spit “wiggity-wiggity-wack” one last time.

The onetime So So Def act, consisting of Chris “Mac Daddy” Kelly and Chris “Daddy Mac” Smith burst onto the scene with their smash hit “Jump,” and are remembered for their baggy and backwards outfits (and perhaps the “Rugrats Rap”).

According to TMZ, the duo has announced that they will be reuniting to perform at a 20th anniversary all-star concert honoring So So Def Recordings in Atlanta in February.

Along with acts like Da Brat and Xscape, Kriss Kross made waves in popular music with label head Jermaine Dupri.
