Rebel Wilson has a new nickname! The 40-year-old Australian Pitch Perfect actress referenced her own role with a new nickname in a selfie posted on her Instagram on Monday (October 5). “Just call me: Fit Amy,” she captioned the post, putting a spin on the original name of “Fat Amy” from the Pitch Perfect movie series. One day before on Sunday morning (October 4), she shared a pic from her morning hike, revealing she’s so close to being at her goal weight.
