The 34-year-old actress took to Instagram to share a picture from the wedding, featuring her kissing her man in the middle of blurry lights and smoke. She captioned the artistic photo, "Nuptials."
Bell shared the same photo with the caption, "Mr and Mrs B."
Mara and Bell met on the set of "Fantastic Four" in 2014. They first fueled dating rumours at the Met Gala in May 2015 when they were spotted holding hands as they made their way into a private after-party. The famous couple have since attended many celebrity events together.
