The wedding was officiated by a man dressed as Elvis himself, who couldn't resist throwing in the odd reference to the late King of Rock n' Roll.
LaBeouf is well known for his performance art so this could be part of a sketch although it looks pretty genuine to us.
The actor is said to have Wednesday his longtime girlfriend Mia Goth in an intimate ceremony in Vegas, with Elvis officiating the ceremony! The couple Wednesday at Viva Las Vegas earlier today, with an Elvis Presley impersonator officiating.
Shia LaBeouf is officially off the market!
LaBeouf and Goth have been dating on and off since 2012 when they met on the set of Nymphomaniac: Vol. II.
The whole event was live-streamed online, and both the bride and groom couldn't hide their happiness as they tied the knot and sealed the deal with a big kiss.
The actors' publicists have yet to confirm if the marriage is for real. A source confirmed their engagement to Us Weekly just days later that the former Disney star did indeed pop the question.
After leaving, he then added: 'If I'd have stayed there, I would have killed her'.
