Is Tyga using Kylie Jenner for her money?

Los Angeles - Tyga has reportedly "borrowed thousands of dollars" from Kylie Jenner.

The 26-year-old rapper - whose money problems have dominated the internet for the past few months - has been dating the 19-year-old businesswoman on and off for over a year but her famous family, including her mother Kris Jenner and sister Kendall, are said to be worried he's using her for cash.

A source explained to Grazia magazine: "The family are increasingly worried that Tyga isn't good news. They worry he's a hanger-on after learning he owes a lot of people money, and has borrowed thousands of dollars from Kylie. She's not the most worldly of sisters and they'd hate to see her taken advantage of."

The couple have even started talking about marriage in recently months and Kris - who also has daughters Kim Kardashian West, Kourtney Kardashian and Khloe Kardashian and son Rob Kardashian - is terrified Kylie will run off to tie the knot without securing her finances with a prenup.

The insider explained: "The couple have even talked marriage and Kris' biggest panic is that Kylie might do something stupid, like elope without a prenup. She's asked Kendall to keep an eye on Kylie and discourage her from doing anything rash."
