The "Bound 2" rapper has spoilt North since welcoming her in June 2013 with wife Kim Kardashian.
Over the holidays that year, the couple gifted her with a mini Lamborghini toy car. He admitted he is picky about what North plays with, reported Us magazine.
"I gave my daughter these toys and I was complaining about some of the toys that my daughter had and I was saying these toys don't have enough quality, soul, life, energy in them," he said.
