Now "Worth It" has amassed another milestone by going double platinum, which the girl group is thrilled about.

With the new certification that means 2,000,000 or more units have been bought.

Monday night Camila Cabello took to Twitter to celebrate the big news!

"TWO PIECES OF IMPORTANT NEWS:" the 5H singer beamed, adding, what she was planning on doing (watching a movie she had not previously seen before) and gushing over "Worth It" hitting double platinum certification!

"2. WORTH IT WENT DOUBLE PLATINUM," she exclaimed, adding, "BUT #2 THO" to really show her shock and excitement.

Savan Kotecha, a songwriter and producer who has worked with the girl group, congratulated Cabello.

Cabello rejoiced in his applause.

She wasn't the only 5H member celebrating the news though. Dinah Jane Hansen also took to Twitter to gush over the double platinum certification of "Worth It," telling her followers, "[T]hank you Harmonizers! This double's for you babes."

She also shared a video a fan took of a violinist playing "Worth It" on the streets of Boston.

The violinist absolutely slays and Hansen knows it!
