Mariah Carey to open for Santa Claus at the Macy's Thanksgiving Day Parade

The 52-year-old pop star - who is known for her groundbreaking festive hit 'All I Want for Christmas is You - and took to social media to alert fans that she will be performing at the annual department store's annual parade in New York City on Thursday (24.11.22.)

She wrote on Instagram: "My childhood dream is coming to life! I’m going to be opening for the one and only, SANTA CLAUS, at this year’s @macys Thanksgiving day parade! Tune in on Thanksgiving Day @NBC."(sic)

Meanwhile, the 'Always Be My Baby' hitmaker - who is mother to 11-year-old twins Moroccan and Monroe with ex-husband Nick Cannon -is set to headline the Madison Square Garden concert 'Mariah Carey: Merry Christmas to All' over the festive period as well as four other shows and explained that she always sets "rules" around Christmas.

She said: "When I’m not onstage and I’m in holiday mode, there are rules that I set. I don’t care who it is – the kids, if I have guests, whatever – nobody is allowed to play or watch anything other than a Christmas-related thing. If I wake up in the middle of the night and walk into the living room, and the music isn’t playing and the lights aren’t on, I just can’t handle it.

"I’m trying to make [these shows] as magical as possible. Oftentimes as a child, or even throughout earlier parts of my career, I did not feel loved. I certainly never felt unconditional love, and that’s what I have with my fans: that connection. So I’m extremely excited."
