Season 19 champion Alfonso Ribeiro is stepping in while Bergeron is spending time with his ailing father, a DWTS source confirms to PEOPLE. “I’ll miss 2morrow’s #dwts to be at my Dad’s bedside. He’s given me a lifetime of support. Time to return the favor,” Bergeron shared on Twitter on Sunday night along with a throwback photo of himself and his father. This will mark Ribeiro’s second appearance on season 21 of the ABC reality dance competition. The former Fresh Prince of Bel-Air actor – and current America’s Funniest Home Videos host – served as a guest judge just last week. “Guest judging on Dancing with the Stars is like returning home for me,” Ribeiro told PEOPLE previously about his return. Dancing with the Stars airs Monday at 8 p.m. (ET) on ABC.
