Pregnancy rumors swirled last December when Tim Duncan showed up to his retirement ceremony with his longtime-girlfriend Vanessa Macias.

Although cloaked in a black coat, many spotted a pregnancy belly. Duncan confirmed in the latest episode of Road Trippin' with RJ and Channing that he and Macias have in fact welcomed their first child together, a baby girl named Quill.

Duncan said the baby was born last week and she was named after Peter Quill from the Marvel Comics character in "Guardians of the Galaxy." He added that the name also made sense because Macias is an avid writer.

"It's a combination of all the things," Duncan said.

Macias chimed in on the birth of her baby via Twitter on Monday.

"Thank you for the love and thoughts welcoming our little soul-changer Quill," she said.

Duncan has two other children, a daughter named Sydney and a son named Draven.
