Taylor Swift absolutely gushed over Travis Kelce down on the field after the Super Bowl on Sunday ... at one point telling him, "You are so magical!!"
The adorable comment was picked up on a hot mic as the two embraced at Allegiant Stadium in Las Vegas following the Chiefs' 25-22 win over the 49ers.
Swift also could be heard in the audio -- which was just released by the NFL -- telling Kelce, "I've never been so proud in my life."
"I can't believe you," she added.
