Kylie Jenner says Tyga is her ''best friend''.

The 17-year-old reality TV star was partying in Cannes, France, with her 25-year-old rapper boyfriend - who she reportedly wants to marry once she turns 18 - and confessed how much ''fun'' she has travelling with him.

Kylie said: ''Tyga's one of my best friends ever so it's so much fun to travel with him. I always like having my friends out on the road with me. He's doing some stuff out in Cannes, so it's just fun.''

The 'Keeping Up With the Kardashians' star was also joined by her mother Kris Jenner, and she admitted she can't keep up with her 59-year-old parent's partying because she is so ''wild''.

Speaking to the MailOnline, Kylie said: ''I love to hang out with my mum as well. She's wilder than me. Last night, I went to bed at midnight and she stayed out much later than me doing her thing.''

Kylie regularly posts stunning selfies on her social media accounts but admits it takes her 500 attempts to perfect the right pose.

She admitted: ''I take, like, 500 selfies to get one I like. Sometimes I regret putting one up if I find a better one later. I'm like damn, that's a better photo, but that's the only thing I regret.''
