Mariah has teamed up with her mum to cover O Come All Ye Faithful.
The duet, which features on Mimi’s Merry Christmas II You album, is being released as a single just in time for the festive season.
While not exactly a household name, Patricia Carey more holds her own against her superstar daughter.
The former opera singer made O Come All Ye Faithful a real family affair – a theme that continues in the video clip (below), which is compromised of old home movies.
Merry Christmas II You is available to buy and download now.
