Idina Menzel is acknowledging the 10th anniversary of her alter ego which was borne out of one of the biggest Oscar gaffes in recent memory with a cheeky serenade.

On Sunday, the Frozen actor shared a short video of herself singing Happy Birthday to Adele Dazeem on TikTok .

I just wanted to say happy birthday. Im sending you so much love and positive energy, Menzel said in the clip. I hope you have the best, best day.

Adele Dazeem first entered the cultural lexicon during the 2014 Academy Awards ceremony, when John Travolta mispronounced Menzels name while introducing her performance of Let It Go from Disneys Frozen.

Please welcome the wickedly talented, one and only, Adele Dazeem, said Travolta at the time, alluding to Menzels Tony-winning stint as Elphaba in Broadways Wicked.

Let It Go went on to win the Oscar for Best Original Song later that night, and Travoltas flub quickly became a viral moment.
