Taylor Swift and her American football-player fiancé Travis Kelce have kicked off rumoured wedding celebrations at Madison Square Garden in New York City. High-profile friends of the couple, from actress Lena Dunham to frequent collaborator Jack Antonoff were spotted Thursday evening in formal attire. Aerial footage showed a stream of black SUVs pulling up to the venue with guests dropped off under a white canopy tent. Media speculation has dubbed the event both a pre-party and possible rehearsal dinner. Around 100 people were expected at the event on Thursday, ahead of a much larger celebration on Friday boasting up to 1,000 guests at the arena. Taylor Swift and Travis Kelce were spotted in New York this week ahead of the suspected celebrations Throughout the day on Thursday, a small army of cops sweated it out in asphalt-curdling heat while camera crews tried to catch a glimpse of anything that would confirm what was happening inside the arena, which is home to multiple sports teams in the city. Celebrity gossip outlet TMZ fired up a live feed of what appeared to be one of the Garden's loading bays, where for several hours one could watch stationary forklifts and the occasional event staffer sneaking a cigarette. Viewers who tuned in at approximately ET ( GMT) could see, in real time, as several men in cargo shorts hauled cardboard boxes from the back of a van.
