When Taylor Falls In Love…

Taylor Swift tended to boyfriend Travis Kelce’s every need after the Kansas City Chiefs’ big AFC Championship victory over the weekend, according to an eyewitness.

Nicole Viscount, the fiancée of Kelce’s former college teammate and roommate Craig Parmenter, told the Delaware News Journal Wednesday that Swift was Kelce’s biggest supporter both on and off the field.

Viscount said that after Swift, 35, ran down to the field to celebrate the Chiefs’ 32-29 win she helped Kelce, 35, kick back in their private suite.

“Once he was in the room, all she did was follow him around to take pictures of him with his family and friends, make sure that he had something to drink and was having a good time,” Viscount told the outlet.

“She was the literal definition of a supportive, happy girlfriend.”

Viscount and Parmenter attended the game alongside the tight end’s brother, Jason Kelce, who also played on the University of Cincinnati football team.

“They are just the best guys. They’re so good at keeping up friendships from their childhood,” Viscount, said of the Kelce brothers.

The 29-year-old said it was a no-brainer when Jason, 37, invited her and her fiancé to both the Philadelphia Eagles game and the Kansas City match-up.

While Viscount and Parmenter, 36, watched most of the game from the stands, they joined the group in their suite before the game ended.

The waitress said Swift’s father, Scott, immediately greeted them when they entered the room. The “Fortnight” singer then quickly went up to introduce herself to the couple, greeting them with a hug.

Swift asked the couple how they knew her boyfriend and Parmeter revealed his close relation to the Kelce brothers as he shared old college stories.

While Viscount — a longtime Swiftie — tried to stay “cool, calm and collected,” she joked that the singer “could probably tell” she was a massive fan “just by looking in [her] eyes.”

When Viscount asked for a photo, Swift “very graciously” agreed, even kissing her cheek for the cute picture.

“I will probably never wash my face again,” she joked.

While it’s unclear if the couple snagged an invite to Prime Social for the private after-party, Viscount later told Jason it was the “best day of [her] life” — and she meant it.

She woke up the next morning and immediately burst into tears.

“It all kind of hit me. And then all day I was just giggling every once in a while because it all seems so surreal,” she said.

“Today I’m just walking around my house trying to figure out how to be a normal person again.”
