Taylor Swift Travels To Super Bowl As Travis Kelce Ex-Girlfriend Parties with 49ers

Taylor Swift Travels To Super Bowl As Kansas City Chiefs' Travis Kelce Ex-Girlfriend Parties with San Francisco 49ers in Las Vegas

LAS VEGAS - Travis Kelce is about to take centerstage here in Las Vegas at the Super Bowl. But in the buildup to The Big Game, his love live and his family life is being deemed worthy of a sidebar or two.

So ... we know that his pop-icon girlfriend Taylor Swift is expected to be in attendance at the game as she travels here following her concert in Japan.

“She’s coming! She’s coming! We’re excited," Gracie Hunt of the Chiefs ownership told PEOPLE magazine at a Super Bowl party in Las Vegas on Saturday evening.

And speaking of partying ... Kelce's ex-girlfriend, Kayla Nicole, has also been spending time in Las Vegas ... and on Saturday night was spotted partying with a group representing the Chiefs' rival in the game, the San Francisco 49ers.

TMZ Sports offers up the details ...

"The ex-GF of Travis Kelce took to Instagram in the wee hours of Saturday morning to share a number of clips from a wicked rager she attended ... and a few familiar faces to 49ers fans popped up in the clips. During the night, Kayla took a shot with some ladies ... and George Kittle's wife Claire threw one back alongside her. George of course is San Fran's tight end -- the same position Kelce plays.''

Nicole dated Kelce on and off for a couple of years before a breakup that didn't really capture any national attention until he began dating Swift ... at which point Nicole made an obvious move to grab some of that extra spotlight for herself.

Meanwhile, Kelce's brother Jason, who plays for the Philadelphia Eagles (and who was in the Super Bowl against these same Chiefs a year ago) is also a center of attention as he ponders a post-NFL career in entertainment. (See below.)

Soon enough, we will have football ... Kickoff at the Super Bowl is scheduled for 6:30 p.m. ET. But for now? The loves and the lives continue as part of the buildup.
