As if Tyga's troubles with creditors, cars and bling weren't enough, the rapper and his girlie Kylie Jenner -- along with his son King Cairo -- went shopping for an ORANGE Lamborghini, on Friday. If you're gonna F up your already horrible credit, go big or go home, right?! Tyga's already had a Ferrari repossessed ... twice, why not a Lambo next!

Tyga and Kylie were dressed waaaay down in brightly-colored sweats for a raining LA afternoon. Kylie donned a Supreme beanie and even grabbed Tyga's hoodie to hide her face at one point. Why, Kylie? Just because you're not rocking a Lip Kit doesn't mean you don't look amazing!

Kylie carried Tyga's and Blac Chyna's son King Cairo out of the Calabasas dealership -- he obviously has Lambo-lover DNA, as was evidenced by his race-car themed 4th birthday party decorated with the Lamborghini logo everywhere.

As Kylie cares for Blac Chyna's son Cairo, she's done more than just babysit for the former stripper -- she gave her and half-brother Rob Kardashian a house! It's already a VERY merry Christmas for Rob and Chyna, moving into one of Kylie's "extra" Hidden Hills mansions. We're guessing Kris Jenner wanted her new granddaughter Dream to be closer to her and wanted to entice Chyna to actually stick with Rob by teasing her with a beautiful home. Well, it seems to be working -- Chyna and Rob just celebrated the renewal of their reality show on social media the other day, rolling around in dolla' bills, y'all, dolla' dolla' bills!
