Rebel Wilson graced the live play of The Little Mermaid at the Hollywood Bowl in Los Angeles on Friday and the 36-year-old Australian star wowed audiences with her portrayal of the classic tale's main antagonist, Ursula, in her final performance on Monday.

The Pitch Perfect star sang alongside a live orchestra, performing classic songs from the 1989 animated classic. Wearing a black sequin gown and high-white wig, Wilson belted out a rendition of Poor Fortunate Souls.

The stage was set up with screens that showed glimpses of the original character and Wilson left audience members in awe with her perfect timing and sync with the animated character being displayed on the screens.

After the show, Wilson took to social media to share a series of photos from her Little Mermaid performance. "Thank you so much to all the fans who came out to see The Little Mermaid in Concert last night," the How To Be Single star wrote on her Twitter page alongside a photo from the event.

She also shared a group picture of The Little Mermaid cast along with a note. "Sooooo much fun working with this incredible cast! And singing such incredible material!" she captioned the photo on Instagram.

Meanwhile, Rebel Wilson was also joined by other Hollywood stars, like Tituss Burgess as Sebastian the Crab, John Stamos as Chef Louie, Sara Bareilles as Ariel, Darren Criss as Eric, Joshua Colley as Flounder and Norm Lewis as King Triton.

The Little Mermaid Live was a three-day show that started on Friday and ended on Monday.
