Clearly anything Kylie Jenner can do, Tyga believes he can do better!

Shortly after the 18-year-old went out and bought herself a Rolls Royce, despite getting a $320k Ferrari from the rapper in August, Tyga did the exact same thing to reportedly prove he's "not a scrub."

“She went out and got herself a fly Rolls and he was proud of that. But not to be outdone, the next day he went out and got himself a Rolls of his own that’s tricked out with the cherry red interior!” a source tells Hollywood Life.

“He’s trying his best not to get bent out of shape when Kylie goes hard on him about his career,” the source shares. “The best part is, he’s about to prove to her that he ain’t no scrub!”
