D'umo (née Cortopassi; born September 11, 1973) and Napoleon Buddy D'umo (born October 17, 1968), known together as Nappytabs, are Emmy Award-winning married choreographers who are often credited with developing lyrical hip-hop.
They are best known for their choreography on the television show So You Think You Can Dance and for being supervising choreographers and executive producers of America's Best Dance Crew.
When Tabitha and Napoleon joined So You Think You Can Dance, dancers on the show, as well as on America's Best Dance Crew and Dancing With the Stars, were already wearing their clothing line during rehearsals.
Some of the sponsors were not happy about it and wanted to cover the Nappytabs logo on the clothing.
In 2003, they joined the faculty of Monsters of Hip Hop dance convention.
Their work was introduced to mainstream audiences in 2008 when they became supervising choreographers on America's Best Dance Crew and resident choreographers on So You Think You Can Dance.
They began their dance career together while still in college by choreographing industrial musicals for large corporations with the hip-hop dance company Culture Shock.After moving to Los Angeles in 1999, they started teaching hip-hop classes at the Edge Performing Arts Center.They took additional jobs choreographing for professional sports dance teams and back-up dancing for musical artists.They did not call themselves Nappytabs, and the word being a nickname to refer to both of them did not start until they became choreographers on So You Think You Can Dance.It was on this show that their lyrical hip-hop choreography style gained mainstream exposure.
Tabitha and Napoleon started dating in 1994, but their professional partnership and dance career did not start until 1996 when they began teaching hip-hop classes together at the Las Vegas Athletic Club.
