Ryan Murphy has been "moved" by Travis Kelce's ambition

Ryan, 58, told 'Entertainment Tonight': "I was just moved by him and his ambition and he wanted to try it and he's a guy who likes to do new things."

Ryan didn't really know Travis before casting him in the series. However, he didn't have any hesitations about working with the Super Bowl-winning sports star.

Ryan shared: "It was very unexpected.

"I did not know Travis, and I thought we were just having a general meeting."

Ryan ultimately wrote a part specifically for Travis and he loved working with the sports star.

Ryan said: "We had a ball, and he's just the most delightful person."

Travis was initially nervous about acting - but he was thoroughly professional in his approach.

Ryan explained: "He showed up off-book. He knew all his lines, he knew all Niecy [Nash-Betts]'s lines. And he was a little nervous at first - as, I mean, I would be too."

Travis has endured a modest start to the new NFL season.

But the Kansas City Chiefs star - who is dating pop singer Taylor Swift - recently revealed how his on-field mentality has evolved over the years.

Travis - who is one of the best-known players in the NFL - said on the 'New Heights' podcast: "I stopped caring about stats about four or five years ago.

"I just went out there and started to play free and play for my guys. Sure enough, I think that's the better mentality. You think about it more play by play and what your job is on that specific play."
