Mariah Carey is giving fans a sneak peek into her holiday plans thanks to a TV takeover.

The singer will be treating viewers to exclusive performances, interviews and a behind-the-scenes look at her Christmas celebrations with 'Mariah Carey's 12 Days of Christmas' on NBCUniversal.

Mariah - who is the best-selling female artist of all time with more than 200 million albums sold - has become synonymous with Christmas time because of her world-famous hit, 'All I Want For Christmas Is You', but has never before given cameras unprecedented access to her yuletide celebrations.

The pop diva - who has two-year-old twins Moroccan and Monroe with her husband Nick Cannon - will be appearing on the 'The Today Show' on multiple occasions, as well as 'Access Hollywood', 'Extra', 'Bravo's Watch What Happens Live' and 'Al Sharpton's PoliticsNation on MSNBC'.

She will also be sharing cocktail recipes, spending time with people involved in her favourite charities including the Make-A-Wish Foundation and the Fresh Air Fund, and allowing cameras into her plush Tribeca triplex in New York City.
