5:30 PM PT -- 2 Chainz shared a video of the wedding party, including Lil Wayne walking behind him and a shot of his bride ... right next to the tiger.
We already knew 2 Chainz' Miami wedding was going to be wild, but he just put the "extra" in extravagant ... by bringing in a damn tiger.
As we reported ... the rapper's dropping a fortune to get married to Kesha Ward Saturday at the Gianni Versace Mansion, and the cost apparently includes having a white tiger on the guest list.
The large striped kitty was seen being rolled up some stairs into the venue in a cage ... and didn't necessarily seem too chill about it. We're told the tiger's caretaker mentioned the Bengal would be switched into another clean cage for the wedding ceremony.
Our source at the scene tells us the caretaker said the tiger would be leaving around 6 PM after the festivities. About 10 security guards were also on hand to assist with the delivery and make sure nobody got too close to the cat.
No word on what the tiger's role will be during the wedding ... but we're guessing it's not ring bearer.
