The San Francisco 49ers' newest and littlest fan arrived at Levi's Stadium when Olivia Culpo and Christian McCaffrey brought their baby girl to the Sunday, September 21, home game. "How cute is this outfit?" Culpo, 33, gushed about baby Collette's first-ever game day ensemble in a TikTok video shared on Sunday. "This is a 2-month baby [and] look how long she is. Go Daddy, yay!" Culpo, who gave birth to Collette in July, dressed her little one in a onesie replica of the Niners team uniform with a red jersey attached to gold bottoms that featured red-and-white stripes along the side.
