In addition to the love from her family, Kotb's celeb friends took to social media to celebrate her birthday. No post was more exciting than the one from Dolly Parton, who sang a personalized song for Kotb in honor of the big day.
"Happy birthday to the wonderful @hodakotb ?," Parton tweeted alongside the video.
"Omg omg omg," Kotb responded. "Thank you @DollyParton"
