Gosling has brought his sister to awards shows on multiple occasions, most recently back in 2008, as she attended the Screen Actors Guild Awards.
Mandi had a prime viewing position, as the world witnessed one of the biggest embarrassing moments at an Oscars ceremony ever.
Gosling’s La La Land was accidentally given the award for Best Picture, as Warren Beatty read out the wrong film.
Moonlight was instead given the award, but only after Gosling and co climbed on stage in an embarrassing mix up.
WOW! #Oscars mistakenly award cast of 'La La Land' Best Picture over 'Moonlight'. Awkward!
