Selena Gomez and Benny Blanco got married Saturday at a place called Sea Crest Nursery in Santa Barbara. Celebrity guests included Taylor Swift, of course . . . plus Selena's "Only Murders in the Building" co-stars Martin Short, Steve Martin . . . along with Paul Rudd, Zoe Saldana, Ed Sheeran, SZA, Camila Cabello, Cara Delevingne, Paris Hilton, Eric Andre, Finneas, and members of Selena's "Wizards of Waverly Place" family.

Sheeran and Taylor reportedly gave speeches at the reception, while Short and Martin . . . (Martin and Short?  Martin and Martin?). . . gave one together at the rehearsal dinner.

Selena was given away by her GRANDFATHER, David Cornett . . . even though her father Ricardo Gomez was there.  There's no word why.

There are some reports that Selena's mom, Mandy Teefey, was devastated that neither she nor her current husband were asked to do the honors, but that doesn't seem to be true. Mandy posted on Instagram that it was "heartwarming" to watch her dad walk Selena down the aisle.

Wanna hear something wild? Selena and Benny reportedly hired the same wedding planner that Justin and Hailey Bieber used. Selena and Benny, who's a music producer, met about 10 years ago.  They got engaged last December. What's next for the happy couple?
