Mariah Carey ditches Christmas sweater to show off diamond bra on Carpool Karaoke

Christmas is still some good two months away, but Mariah Carey already seems to be in the mood for some festive dressing. The All I Want For Christmas Is You singer was recently spotted with chat show host James Corden as the two filmed for a Christmas special segment for the Late Late Show.

While the English actor-cum-TV host was dressed in an oversized green holiday sweater, Carey's outfit was anything but traditional. The 46-year-old songstress sported a diamond-studded bra as she shot for the immensely popular Carpool Karaoke segment of the show.

She opted for a red Balmain leather jacket as her top along with a pair of fitted denims. To add to the edginess of her attire, Carey zipped her jacket low to show off the diamond-encrusted bra that also features a bejewelled chain falling from her neck to her navel.

The mother-of-two accessorised her looks with shiny hoops, dark shades and a pair of tie-up heels.

While Corden too endorsed the festive spirit, his traditional "ugly" sweater was no match to the We Belong Together hit-maker's much contemporary look.

Both of them were later seen driving around in the signature black SUV possibly singing festive tunes for the Christmas-special episode. So much so, that even the Carpool Karaoke's car donned holiday decoration in the form of a giant Christmas tree sitting atop the roof.

According to People magazine, the undated episode might feature one of Carey's iconic songs - All I Want for Christmas Is You from her 1994 album Merry Christmas.

The Late Late Show with James Corden airs from Monday to Friday at 12.30am EST on CBS.
