"That's not my baby! She doesn't look like me," Ice T, 58, joked of nearly 4-month-old Chanel's light complexion.
"She's a little model," Austin, 37, gushed. "I've got the camera in her face at all times."
The Law & Order: Special Victims Unit actor and Austin welcomed their baby girl in November. She came one month early, weighing in at 5.7 pounds.
The late-night host, 41, was more than excited to meet the little one Wednesday — even though Chanel slept through it all! Nonetheless, he obliged when Austin asked him to pose for a pic with the newborn.
"I have to be close to the floor," Fallon joked, as he sat on the ground. "I don't want to let go of her. This is the best thing ever." (Ice T is also dad of daughter Letesha and son Tracy from previous relationships.)
Ice T didn't miss a beat. He quipped: "[Chanel], say hello to your rich uncle!"
