No official documentation of Shia LaBeouf's marriage to Mia Goth?

Washington D.C.: Internet goers recently witnessed a livestream video feed of what looked to be a wedding between Hollywood actor Shia LaBeouf and his longtime girlfriend, Mia Goth in Las Vegas.

The couple appeared to say "I do" at the Viva Las Vegas chapel in Sin City at a Vegas-themed ceremony, reports E! Online.

The video also showed some onlookers who were dressed in costume, including an Elvis Presley impersonator.

Though the video certainly looks real, however, the 30-year-old actor is also known to be into performance art.

There is still no documentation of them officially marrying.

The 'Transformers' star first started dating the British actress and model in 2012 after meeting on the sets of Lars Von Triers directed movie, 'Nymphomaniac.'

Soon after, rumours began swirling that the couple got engaged in March 2015 after Goth was spotted wearing a ring on her finger.
