Britney Spears Not Joining The Weeknd's 'The Idol' ... Despite Fan Theory

Britney Spears fans hoping to catch a glimpse of the singer in The Weeknd's new project with HBO won't have their way ... because she's simply not involved, TMZ has learned.

Britney set social media on fire Tuesday when she announced, "I just shot a movie titled “THE IDOL“ … it’s guaranteed to have hits and a lot bright pics to put in my beautiful family’s faces !!!!!"

Spears' announcement came hours after it was announced The Weeknd's show "The Idol" was getting the green light from HBO and singer Troye Sivan had joined the cast.

Of course, fans were quick to connect the two, believing Britney was signed on to the project as well, but sources with direct knowledge tell us it's just not the case.

Our Britney sources say she's not been asked to be a part of the HBO show, and her team is unsure as to what movie she's referring to in her caption. Britney's been very creative with her social media posts lately, so it's always possible she's producing a movie on her own at home.

Britney also sent a message to her fans about the upcoming holiday season, saying, "I hope you guys are having a merry ole jolly time cause I sure am !!!!"
