E! News can confirm the Hollywood stars tied the knot in Los Angeles over the weekend after dating for over two years.
Mara took to Instagram to share a pic from the wedding, featuring her smooching on 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."
Meanwhile, Mara and Bell met on the set of Fantastic Four in 2014. They first fueled dating rumors at the Met Gala in May 2015 when they were spotted holding hands as they made their way into a private after-party. That September, they were photographed getting cozy on a beach in Malibu.
A month later, they were seen kissing on a street corner in New York City, which seemed to cement the romance rumors.
The famous couple have since attended many celebrity events together, including the H&M Womenswear Fall/Winter 2016/2017 show at Paris Fashion Week, the 2016 Met Gala, and the Hollywood premiere of the actress' movie, Man Down, in November.
