But Katy Perry’s likeness to Father Christmas’ wife stopped there as it wasn’t long until she whipped off the garment to reveal a sexy leotard as she headlined the Capital FM Jingle Bell Ball at the O2 in London.

And in keeping with her racy look the 29-year-old well and truly warmed up proceedings by bumping and grinding on stage allowing the fringed leotard to take full effect.

Covered up: Katy Perry started off her performance at the Jingle Bell Ball in London on Saturday evening wearing a fur trimmed coat

Phwoar: She stripped off to reveal a sparkly pink leotard beneath which showed off plenty of preview

The American singer’s leotard was pale pink and covered in sequins so it shimmered every time she moved.

Around the bottom area it was covered in pale pink fringe detail, as well as beneath the sleeved arms.

Showing off her incredible figure it was very low-cut, giving the audience more than a glimpse of her ample cleavage.

Stunning: Katy Perry looked elegant in the shimmering blue coat which looked something Mrs Claus would wear

Fur trimmed: The coat was particularly festive due to the large white fur trimmed sleeves and collar

Making sure the dress took centre stage, her hair was sleeked off her face in a ponytail which swung about as she moved around.

The songstress started her performance with her debut single and firm favourite I Kissed A Girl.

It was straight on to new songs from there with Prism and Dark Horse, before she was joined by a group of futuristic looking elves for Part Of Me.

Her set also included Wide Awake, as well as, amongst others, Teenage Dream –  much to the delight of the audience.
