The 26-year-old rapper was hauled into a hearing by celebrity jeweller Jason of Beverly Hills to see how he can pay off a $200,000 judgment for a diamond encrusted watch and chain.
The Rack City hit-maker was apparently fine answering questions about his finances until the topic came to Kylie, TMZ reported.
The jeweller, Jason Arasheben's lawyer, Alexander Cohen began by asking the beau of the 19-year-old reality star about property he owns and his income.
Tyga - which is an acronym for Thank You God Always - was accommodating and answered the attorney, despite flashing his middle finger and pretending to aim a gun towards cameras as he entered the building.
However, when he was asked how much he spends on gifts for his reality star girlfriend, Tyga claimed to feel ill and had lost his memory, according to TMZ.
His hearing has been rescheduled for November 1 which also happens to be the same day Kylie is set to come in for her own questioning.
