Project Runway judge Nina Garcia's second son made his debut in New York City this weekend.
"Delighted to announce that over the wknd we welcomed 8lb13oz Alexander David Conrod into our home!" Garcia, 45, wrote on Twitter.
"Baby is doing great & Lucas is thrilled!" she added, referring to her 3½-year-old son with husband David Conrod.
And Lucas had been excited about the impending arrival for some time. "He's excited and he gets it," Garcia told PEOPLE this summer. "We told him, and he's very happy to be a big brother. He's waiting for the baby to come more than we are."
In addition to her role on Lifetime's Project Runway, Garcia is also fashion director at Marie Claire magazine.
