The 61-year-old journalist visited Kotb and her baby on Thursday, and was quickly deemed the "baby whisperer."
"Maria Shriver came by and Haley Joy was MESMERIZED! Love you," Kotb captioned a selfie of Shriver feeding Haley a bottle.
Clearly impressed with Shriver's connection with her daughter, the Today show co-anchor posted another pic, writing: "MESMERIZED!!!"
Shriver was also thrilled to meet Haley, and shared the same selfie on her Instagram. "The absolute best way to spend your time," she wrote. "So proud of you @hodakotb and soooo happy for you!"
