Taylor Swift and Travis Kelce’s award-winning alchemy returned to Las Vegas this weekend for a Kansas City Chiefs reunion this weekend to party with Patrick Mahomes and his wife, Brittany. Fresh off the heels of the release of Swift’s latest album, the Grammy Award winner and three-time Super Bowl champ partied with the star quarterback and retired pro-soccer player  at Easy’s Cocktail Lounge inside the ARIA Resort, sources with direct knowledge told TMZ on Saturday. This isn’t the first time the couples have gone out together in Sin City, with some much-publicized partying there to celebrate the Chiefs’ Super Bowl win against the San Francisco 49ers in February. Later that month, Kelce left Sydney, Australia — where he’d been for one of the legs of his girlfriend’s Eras Tour — to head back to Las Vegas to continue celebrating with Mahomes. The latest Vegas date comes a week after Swift dropped her surprise double-album, “The Tortured Poets Department,” whose songs are in large part believed to stem from her brief but fraught love story with The 1975 frontman Matty Healy. However, the tracks “The Alchemy” and “So High School” are both believed to be about Kelce. In the run-up to the release, the superstar couple doubled with another A-list pair — Swift’s longtime pal Gigi Hadid and Oscar nominee Bradley Cooper, to whom Hadid has been linked since the fall.
