Travis Kelce won't propose to Taylor Swift until the couple have agreed a prenup. Swift is a billionaire - thanks in no small part to her Eras Tour - while Kelce has an estimated worth of around $70 million. Now, according to a source quoted by Life and Style, the couple are ready for the next step but Kelce won’t pop the question until financial terms are in place for if they were to ever split up. “This is a lot further along than either Taylor or Travis would care to admit, since they’ve considered themselves unofficially engaged for a while and are both 100 percent committed to spending the rest of their lives together and starting a family,” the source is quoted as saying. “The formalities are just their schedules that have gotten in the way, as well as the logistics of a prenup, which is obviously complicated by the vast amounts of money involved on both sides. There’s just no way Taylor would walk down the aisle without a prenup. They both want it figured out before Travis gets down on one knee.”
