“Pitch Perfect 3” star Rebel Wilson (Fat Amy) celebrated her birthday on March 3 on the set of her upcoming film. The actress had a unique celebration as instead of blowing a candle, she fended off dogs while wearing a black protective suit.

Wilson was generous to give fans a glimpse of how she celebrated her birthday. She posted a clip of her as she bonded with the dogs. “Happy Birthday to me,” the actress captioned her post.

In the clip, two dogs can be seen clawing away at her arms. There were some instances in which she seemed to have lost her cool. Wilson can be heard screaming, “Seriously?”

The actress had also recently shared her secret for weight loss. She has taken to the same social media platform to reveal that it was marathon hiking that helped her drop the unwanted fats. She also shared that she has been receiving massages, which makes her feel great. “Thanks to the amazing staff and masseuses (free daily massages are part of the program)! Feeling great,” she wrote on Instagram.

Wilson works alongside Anna Kendrick (Beca), Hailee Steinfeld (Emily), Chrissie Fit (Flo), Kelly Jakle (Jessica) and Ester Dean (Cynthia Rose) in the film. They are part of an all-female a capella group called the Barden Bellas.

The self-confessed “Glee” fan had previously hinted about what to expect from her character in the film, saying she thinks Fat Amy origins story would be awesome. Fans of the franchise know that her character is the picture of a bullied girl. It is expected that the threequel will see how Fat Amy has endured unkind words as a young girl.

Furthermore, Wilson has told the Hollywood Reporter that she would like to do something in which she plays a female rapper. Since the Barden Bellas will be having new competitors in the upcoming movie, there is a chance that Fat Amy will try new things such as rapping to get an edge.

Rapper James Trinidad was confirmed to join the film. He will be part of a group that will compete against the Barden Bellas. Since Wilson has shown willingness to rap, it seems she will be the Barden Bellas’s bet to defeat James’ character, which is still unnamed.

Trish Sie directs the film with a script written by Kay Cannon and a draft from Mike White. "Pitch Perfect 3” is expected to hit Australian theatres on Dec. 22.
