Mariah Carey is whippin’ up a new holiday treat…

The 50-year-old half-Venezuelan American singer, known as the “Queen of Christmas,” is teasing fans with a holiday gift,

Carey took to social media and shared a photo of three director’s chairs on the set of a project, with a Christmas tree emoji as the caption. The chairs feature the letters “MC,” “AG” and “JH,” and while MC are obviously Carey’s initials, fans are buzzing over who the other two collaborators could be.

The most prominent fan theory seems to be Ariana Grande and Jennifer Hudson, while some are also suggesting that “JH” might be J-Hope from BTS. Carey has yet to officially confirm her two collaborators.

If the guesses are correct, this would hardly be Grande’s first dip into the Christmas pool. The star has released two holiday collections, 2013’s Christmas Kisses and 2015’s Christmas & Chill, plus her 2014 track “Santa Tell Me.”

In 2009, Hudson hosted a holiday special, I’ll Be Home for Christmas, in which she headed back to her hometown of Chicago, joined by Michael Bublé, for Christmas memories and music.

Carey scored her 19th No. 1 on the Billboard Hot 100 last year with her 25-year-old insta-classic holiday song “All I Want for Christmas is You.”
