"Cobra Kai" stars Tanner Buchanan and Mary Mouser are getting married.

The two stars of the hit Netflix show announced the news Wednesday night at the premiere of the "Cobra Kai" series finale in Hollywood, California.

Buchanan and Mouser were all smiles as they hit the carpet and showed off their rings.

They also shared a kiss as they posed for photos on the carpet.

Following the event, they shared a joint Instagram post Thursday about the news and wrote in the caption, "We're so happy to finally share that we're engaged."

"This is such a special moment in our lives, the closing of one chapter and celebrating the continuation of another," they added. "We’re so grateful for the love and support, and though we’re partial to having our private moments, we’re excited to share this check-in to our world ????"

Mouser also took to her Instagram story and wrote, "friends to lovers trope achieved," alongside a photo of her and Buchanan.

The show also stars Martin Kove, Xolo Maridueña, Jacob Bertrand, Peyton List, Gianni DeCenzo, Courtney Henggler, Vanessa Rubio, Dallas Dupree, Yuji Okumoto, Alicia Hannah-Kim, Oona O'Brien and Griffin Santopietro.
