Christina Aguilera has strutted her stuff this festive season and transformed into a sexy Santa.

The singer put a racy twist on the traditional red and white outfit as she posed under a giant Christmas tree in a curve hugging onesie and towering black heels.

Christina shared two pictures with her 3.6 million followers on Instagram, each featuring the star playfully posing up a storm as she put her long legs and toned bum on display as she debated which list Santa Claus will put her on.

She captioned one ‘nice’ and the other ‘naughty’ – with the latter looking like it won the approval of her fans with 159,000 likes on the social media site.

One cheeky follower joked: “Why didn’t I marry you when I had the chance…”

It comes after Kylie Jenner proved herself to be one of Christina’s biggest fans ever this year.

After dressing up as the singer for Halloween, the reality star has gone and done it again in celebration of Xtina’s 35th birthday .

Wearing the singer’s outfit from her iconic Dirrty music video, Kylie took to Instagram to share a video of herself hanging out with the pop star, all while dressed as her.

Sitting on Christina’s lap in a short clip shared on Instagram, the two stars shared a quick peck on the lips as they partied the night away.
