Kylie Jenner posts cryptic video after dumping Tyga on his birthday 'over something he did'

She broke up abruptly with him on his 26th birthday on Thursday.

Kylie Jenner certainly didn't shed any more light on the reason for the break-up come Friday.

The 18-year-old continued the mystery as she posted a cryptic video on Instagram that saw her miming the lyrics to Bryson Tiller's tune Been That Way.

Kylie is seen giving the lens a sultry-eyed look while a make-up artist applies lip liner to her plump mouth, before singing, 'I wanna know why we became so distant girl?'

She's outdoors and it's a sunny, beautiful day, and she's got the music blasting.

Perhaps the tune is no coincidence, as one follower points out, writing, 'The song is bryson tiller been that way. Pretty sure she keeps playing it because she feels that way about tyga.'
