Kylie Jenner says she's 'high as f***' in new video as Tyga's grandma says she approves of their relationship

Well, her boyfriend is 25, so if she's drinking and getting 'high as f**8',  no one should be surprised. The 17 year old reality star was seen in a brief video posted on snapchat whispering ‘I’m high as f***.’ as she gazed off camera while on a trip with Tyga.

Meanwhile Tyga's grandmother has given Kylie the seal of approval. 70 year old Kim Nguyen said she couldn't be happier that her grandson has traded Blac Chyna in for the 17 year old star. Talking exclusively to Daily Mail Online from her home in Los Angeles, the woman said;

'We all love Kylie and think she is so much better for Tyga than Blac. Yes she is King's mum, but Blac just wasn't a very nice person and Kylie comes from a much better family. She is such a sweet, lovely girl and seems to adore Tyga. So we didn't mind him splitting up from Blac. It was a relief for us all.'
