Shia LaBeouf has married his longtime girlfriend, Mia Goth, in a Elvis-themed Las Vegas ceremony. To make matters weirder -- it looks like they live streamed the whole thing! WEIRD!

The couple said "I do" at Viva Las Vegas, a chapel known for their themed weddings, including a gladiator, mafia and Alice Cooper themes. It appears as though Mia and Shia opted for the King theme. The short ceremony included some Elvis covers, as well as a classic Bruce Springsteen tune.

While this may be a shotgun wedding, both Shia and Mia's moms were in attendance. We'd say the whole thing was sweet -- but really it's just weird.

Shia and Mia got together in 2012, after meeting on the set of Nymphomaniac: Volume II. Last year, they got into a headline-making fight while in Germany, however, Mia was spotted wearing her wedding ring back in March.

Umm congrats to the happy couple?!
