The rapper is romancing British lingerie model Demi Rose Mawby - and she is STUNNING!
Kylie, you may want to look away now…
Demi Rose is from Sutton Coldfield in Birmingham, but moved to Miami to make it as a model a year ago.
The pretty brunette – who is the daughter of a bank manager - studied health and beauty at college, before going into modelling.
She was seen heading to a party with Tyga in Cannes, wearing a see through outfit that showed off her underwear and incredible curves.
Tyga – real name Michael Ray Nguyen-Stevenson – then confirmed their romance by posting a picture of the pair on his Snapchat.
His new 21-year-old girlfriend is already an internet sensation – she has 2.3 million followers on Instagram and 324,000 on Twitter.
That pales in comparison to 18-year-old Kylie though – she has a massive 61.5 million followers on Instagram and 16 million on Twitter.
Kylie and Tyga confirmed their romance at the start of 2015 and he's featured in Keeping Up With The Kardashians, while she's starred in one of his music videos.
But the pair split earlier this month, shortly after Kylie's brother Rob Kardashian announced he's expecting a baby with Tyga's ex Blac Chyna. She already has a three-year-old son, King Cairo, with Tyga.
Speaking shortly after the split, Tyga said: "We're both focused on our individual lives right now and sometimes things don't work out, but I love her."
Well it didn't take him long to move on!
Meanwhile, Kylie appears to be enjoying the single life, partying with her sisters Kourtney and Khloe in West Hollywood on Friday night (May 20).
