Architect-turned-designer Laura Bennett, a finalist on the third season of Project Runway,
has welcomed her sixth child, a boy, she tells PEOPLE exclusively.
Her son Finn was born at 10:46 a.m. on Friday, Dec. 1, and weighed in at 8 lbs. Bennett says her newest child is "so cute" and that she is feeling fine.
Already a mom to four sons and a daughter (daughter Cleo, 18, from a previous marriage and sons Peik, 10, Truman, 7, Pierson, 4, and Larson, 3), Bennett, 43, discovered she was pregnant while filming the Bravo reality competition.
She didn't fuss about not having maternity clothes with her: "I'd wear these stretchy T-shirt dresses," she told PEOPLE in September.
After the Project Runway finale
in October, Bennett awaited her baby's arrival at home in Manhattan with her husband, Peter Shelton, 61, who runs a design firm.
"Poor guy, he was the last to know," Bennett, a New Orleans native, told PEOPLE. "(Michael Kors's mother) Joan knew, but my husband didn't!"
