The Fresh Prince of Bel Air star Alfonso Ribeiro has welcomed his first child with second wife Angela Unkrich.

Riberio, who is best known for playing Carlton Banks in the 90s sitcom, took to Twitter to announce that Unkrich had given birth to a baby boy on Twitter.

"Alfonso Lincoln Ribeiro Jr was born today at 10:45am. We are so blessed," he told his 33,700 followers.

The actor-turned-director paid tribute to the doctor who delivered his son.

He said: "We also want to thank our amazing Dr Jason Rothbart. He was great and a calming influence in the room.

Ribeiro, who married Unkrich in October 2012, already has an 11-year-old daughter, Sienna, by his ex-wife, Robin Stapler.

"They are all healthy, happy, and exhausted," Ribeiro's spokesperson told Us Weekly magazine.

In September, Alfonso revealed that the couple had decided not to find out the sex of their child before it was born.

"We still don't know the gender as we decided to hold out and be surprised," he told People magazine.

"One thing we know is that it's a very active baby. He or she has been kicking and punching around the clock. It never gets old to see the little feet imprinted on the belly during the kicking episodes."
