Selena Gomez's Big Surprise? She's the New Face of Pantene

THIS is Selena Gomez's "BIG announcement?!"

Is Selena Gomez's recent big reveal putting her at risk of getting some major backlash a la Beyonce?

After teasing a "BIG announcement" on her Instagram on Sunday -- which based on the short video of a cameraman, plenty of fans assumed was perhaps a new music video or even a reality show -- the news turned out to be that the 22-year-old star is the new face of Pantene.

"I am so happy to announce my new partnership with Pantene! #SelenaxPantene #strongisbeautiful," she tweeted on Monday.

Selena shakes her dark locks for the behind-the-scenes video of her new campaign, and explains why she's excited to be Pantene's new ambassador.

"The three reasons I'm excited to be Pantene‘s new ambassador are I've used it my whole life; and second, their message for women being strong is beautiful and what they represent is so what I embody and want my fans to know, to feel confident; and third, it's fun," Selena says. "It's so fun to feel like your inner girl, playing with your hair and just feeling beautiful.”

She also Instagrammed this super-cute video of her getting her hair done for the ad.

Regardless if you're disappointed with her big tease, you have to admit, Selena does have great hair!
