'NO, I'm not engaged!' Kylie Jenner, 18 ~ Lafkillz

Kylie Jenner shared a photo of a very large diamond engagement ring on Christmas day.

The 18-year-old wore the bling on her right hand as she held onto the steering wheel of her Range Rover.

But she has now come out to hush rumours of a possible engagement to Tyga as she wrote on her website on Saturday, 'NO, I'm not engaged.

'Every year my Mom throws a huge Christmas Eve party and this years was so fun (and sparkly)! It was really special to end such a big year celebrating with all of my friends and family... and with an extra special gift from a special someone,' she wrote on her site.

Then added: 'And NO, I'm not engaged'.

Two nights before the teen shared a snap where she was kissing beau Tyga at mom Kris Jenner's Christmas Eve party in Hidden Hills.

There has been reports Kylie and Tyga were on the outs, but the smooch proved they are very much on.

E! News reported on Thursday the two are back on but taking things 'lighter.'
