Forget the ice bucket, mannequin and no make-up challenges of years gone by.

2017 has just ushered in a new challenge and it might not be one to challenge your parents to take part in.

Celebrities and their fans from around the world are now taking part in 'For The D' challenge (though boys are calling it 'For the P'), which comprises of rapping about what they'd do for sex.

Everyone from the likes of number one rapper Cardi B, Issa Rae, Tyga have taken part in the challenge, inspired by New Orleans rapper GameOva Reedy's freestyle song 'For That D'.

The latest star to join in on the fun is Kim Kardashian, who last night took to Instagram to share a picture of herself and an explanation of why she recently went platinum blonde.

In the caption for the post, which sees the 36-year-old sport long ice-blonde hair and a pair of jogging trousers, the message reads: 'I'd go blonde for that D.'

In response, her younger sister Khloé commented: 'You're sooooo obsessed with that D.'

The post comes almost a week after Tyga rapped alongside Keke Palmer in an Instagram video for the challenge to dispel rumours he is the father of Kylie Jenner's rumoured baby.

'The baby mine? Hell no, for that pussy,' he rapped.
