The Keeping Up With The Kardashians star wanted to treat her hubby to a lavish celebration so she arranged for the whole of the arena to be shut off so they could celebrate in private and in style!
Kim kept Kanye guessing right up until the last minute, making him wear a blindfold as they drove to the venue.
When he arrived, all his friends – including John Legend and Justin Bieber – were dressed in basketball kits and ready for their very own play off!
Kimye also nabbed a picture with the Laker Girls, which Kim captioned: "Thank you Staples Centre for the most amazing birthday party for Kanye!"
Earlier in the day, pregnant Kim had paid tribute to her husband with a very sweet Instagram post.
Kim wrote: "Happy Birthday to my best friend in the entire world! You are the most amazing husband & dad! You inspire me every single day! You make all of your dreams reality & it's fascinating to be by your side & watching it all happen! You have a heart of gold! Have the best birthday ever! #SWISH."
Kim, 34, and Kanye married in Florence, Italy in May last year. They have one child, North, who turns two this month. They'll welcome their second child later this year.
