The Fantastic Four's Invisible Woman and The Thing are getting married!
The news comes soon after Mara was spotted walking in New York City wearing a ring with a large stone on her ring finger.
She also wore a sparkling ring in a photo posted on Twitter this past weekend.
The 33-year-old actress and Bell, 30, had sparked engagement rumors last year after the actress was seen wearing a ring on her ring finger. When asked then if they were engaged, the British actor told E! News, "No," while the actress chucked at the question.
