The stars are all dolled up and celebrations are underway at Taylor Swift and Travis Kelce's mind-blowing wedding bonanza at Madison Square Garden for what is expected to be the party of the century.
Bradley Cooper kicked off the glamorous arrivals in a dashing tuxedo, while the bride prepared with rumored bridesmaid and best friend Gigi Hadid in her downtown Manhattan home.
Mega-watt celebrities Jay Z and Steven Spielberg jetted into the city on helicopters from the Hamptons ahead of the big bash.
Swift and Kelce partied late into the night on Thursday for their 'rehearsal dinner' with 100 of their closest friends, including Hadid, her partner Cooper, Selena Gomez and Jack Antonoff.
There are conflicting reports about whether Swift and Kelce have already married, but an enormous party with 1,000 guests at Madison Square Garden kicked off in the early afternoon today.
Guests started to arrive at the venue at 3.30pm ET, and city permits suggest the extravaganza could go on until 4am.
Industry experts claim the nuptials cost more than $15 million, including the venue, security, insurance, permits, catering and decorations to transform the venue into their fairytale wedding.
Taxpayers contributed over $1 million to pay for the couple's NYPD security detail patrolling MSG, which banned the press from getting too close and threatened to arrest anyone who did not comply with street-closure rules on Thursday.
