A fresh little prince or princess is on the way for Alfonso Ribeiro! The Fresh Prince of Bel-Air actor and wife Angela Unkrich are expecting their first child together.

The 41-year-old star announced the baby news on Twitter Wednesday, May 1. "Coming this fall: a baby Alfonso or a baby Angela!" he wrote with a split WhoSay photo of his and Angela's baby pictures.

Ribeiro is already dad to 9-year-old daughter Sienna with ex-wife Robin Stapler. He and Unkrich, 31, tied the knot in October 2012 at a ceremony in Los Angeles with his Fresh Prince costar Will Smith as a groomsman, alongside 'N Sync singer Joey Fatone and baseball player David Justice.

The parents-to-be celebrated their six-month wedding anniversary in April. "So happy to be with my wife on our anniversary at TPC Sawgrass," Ribeiro tweeted about the Florida golf course. "Great to be with the love of your life."
