Christian McCaffrey Interview on Olivia Culpo, Baby Colette

Christian McCaffrey and Olivia Culpo‘s squad got a new member over the summer: daughter Colette.

Since then, the NFL player and the Culpo Sisters star have been soaking up every minute they can with their baby girl.

“Watching your daughter grow has been the coolest thing in my life,” Christian, who recently partnered with Intuit, told E! News in an exclusive interview. “Watching her develop a personality, start to notice the world, smile, move. It’s been awesome.”

“I love her so much,” the San Francisco 49ers running back continued. “My wife loves her so much.”

As for who the 6-month-old resembles?

“Some days I’m like, ‘Man, she’s my twin,'” the 29-year-old shared. “Other days, I see she’s a Culpo. I can see the eyebrows and the eyelashes.”

“And then from a personality standpoint, we’re very similar, but different in a lot of ways,” he added. “It’s starting to come out more, and we’re noticing different things every day.”
