Travis Kelce and Taylor Swift's romance has been the background to this entire NFL season and it culminated in a passionate Super Bowl kiss after the Chiefs won the game against the 49ers to go back-to-back. After all the talk during the season about how the Kansas City tight end's performance was dropping, here he was again on the top of the world.

There have been doubts about Travis Kelce's abilities this season. He was injured to begin the season and finished with fewer than 1000 yards in a long time. He also raised the prospect of retirement, citing all the injuries he has had over the years, after he started dating Taylor Swift. There were murmurs around the league whether his relationship was affecting his play.

Instead, Taylor Swift has been there by him whenever she can and she has been rewarded seeing her boyfriend win the Super Bowl again. The tight end has been a phenomenon during the postseason and kept coming up with big plays whenever they needed him. And after lifting the Lombardi Trophy, he went straight to his partner and embraced her.

It was a passionate moment caught on camera and it served as a perfect finale for many. NFL has added new supporters due to her presence at games and it seemed fitting that she was there to celebrate it with him. You can watch the moment below.
