Watching Taylor Swift and Travis Kelce together is like witnessing a fairytale unfold. Love truly knows no bounds..

Almost everyone who knows Travis Kelce well — from his childhood BFF to Kansas City Chiefs quarterback Patrick Mahomes — uses the same phrase to describe him: “the life of the party.” After winning his third Super Bowl, he belted out “Viva Las Vegas” to 60,000 people in the stadium, including his girlfriend, Taylor Swift (and another 123 million viewers at home).

While back in Sin City to celebrate with his team at XS Nightclub on February 24, the tight end wore a WWE-style championship belt, sprayed fans with champagne and boozed until 4:15 a.m. At a Cleveland Cavaliers game on March 5, he lost a beer-chugging competition to his older brother, Jason. Wherever he is, says a source, “Travis definitely likes to have fun.”

Those close to the football star — including several ex-girlfriends — are exclusively telling In Touch about Travis’ wild side. Taylor, 34, “may be in for a shock,” says the source, noting that Travis has downplayed past mistakes and hasn’t exactly stopped flirting with other women since they met eight months ago. “He’s in love with Taylor, but there’s a side to him that she doesn’t know about.”
