Demi Lovato topped off her birthday celebration with the announcement that she's joined the cast of Eurovision, an upcoming Netflix film starring Will Ferrell, Rachel McAdams and Pierce Brosnan.   

The David Dobkin-directed comedy is based on the famous Eurovision Song Contest, an annual song competition.   

On Tuesday (Aug. 20), Lovato's 27th birthday, the singer shared the news via an Instagram video announcement from Ferrell on the set of Eurovision.

"We want to make a very special announcement about a brand-new cast member, and it just happens to be her birthday today," Ferrell said. "I made her this wonderful cake from scratch. So happy birthday! Yay!" 

The clip then cut to Lovato blowing out birthday candles next to a Eurovision film slate. 

"y’all, Will Ferrell made me a cake...from scratch. It looks completely professional and store bought so I’m not at all suspicious that he baked it himself in all of his free time #netflixisajoke #eurovisionmovie," she captioned the Instagram post.
