The 'We Belong Together' singer – who is believed to be expecting her first child with husband Nick Cannon – has recorded her second festive LP, entitled 'Merry Christmas II You', and will release it on November 2.
Produced by 'American Idol' judge Randy Jackson, James Poyser, Jermaine Dupri and award-winning composer Marc Shaiman the LP will feature Yule-tide classics such as 'O Little Town of Bethlehem', 'The First Noel' and 'Little Drummer Boy', as well as four original songs composed by the pop beauty.
A new version of Mariah's most famous seasonal track 'All I Want For Christmas Is You' – which featured on the album 'Merry Christmas' - will also appear on the album.
Despite having been first released in 1994, 'All I Want For Christmas Is You' continues to appear on the Billboard Hot 100 Recurrent Singles chart each Christmas, hitting the number one spot every year from 2005 to 2008.
It is still not clear whether Mariah and Nick will be preparing for the patter of tiny feet by Christmas time.
Although she is widely rumoured to be pregnant, the singer refuses to publically confirm or deny the news.
Last month, she posted on her website: "I appreciate everyone's well wishes. But I am very superstitious. When the time is right, everyone will know."
