The stars are all dolled up and on their way to 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 Bradley Cooper, Selena Gomez and Jack Antonoff.
There are conflicting reports about whether Swift and Kelce have already married, but there are plans for an enormous party with 1,000 guests at Madison Square Garden today.
Guests started to arrive at MSG at 3.30pm ET, and the festivities will kick off around 5pm. City permits suggest the extravaganza could go on until 4am.
Industry experts claim the nuptials cost over $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 press from getting too close and threatened to arrest anyone who did not comply with street closure rules on Thursday.
A few glimpses of the interior were visible. Pink, orange and yellow roses were photographed woven into foliage at the top of an escalator.
Crews are now working feverishly to turn around the decor for night two of the festivities.
