The Petty Award for the week goes to Blac Chyna and Tyga who both threw Ferrari themed birthday parties for their 4-year-old son King Cairo one day apart...
Based on Kylie Jenner and Blac Chyna's SnapChat stories Tyga definitely spent more money, but Blac Chyna's party had more kids.
Fun Fact: Tyga's guest list included North West.
