“Kylie’s been aware of Tyga’s financial problems since she began dating him,” a source tells HollywoodLife.com, adding that these financial problems include owing over $130 thousand dollars in back rent and trying to keep up with the Kardashian’s lavish lifestyle.

“Thus far, Tyga’s tab is close to half a million dollars and counting. [And was] one of the reasons they broke up.”

What’s more, we’re told the Make It Nasty rapper has told Kylie that “they are a unit, and couple, and… that if she truly loves him, then money shouldn’t matter.”

Or maybe he should stop splashing out on expensive cars!
