Birthdays must be hard for Kim Kardashian and Kanye West.

After all, both Kardashian and West are extraordinarily wealthy and could buy virtually anything they want. So, what sorts of present do they get each other?

Kardashian answered that question Monday by renting out Staples Center for her husband's 38th birthday. The gift reportedly cost $110,000.

Kim's younger sister, Khloe, sent out this image from the game:

Kanye isn't exactly known for his perpetual smile, so the fact that he's grinning in this picture means he's probably pretty happy.

Not only did Kardashian rent out a world class arena for her husband, she got a Grammy-award winning singer to sing the national anthem and "Happy Birthday." Here's Kanye's good friend John Legend:

According to Us Weekly, NBA stars Russell Westbrook, John Wall and James Harden joined Justin Bieber and a host of other celebrities at the event.

But Kardashian didn't stop there. According to TMZ, she got actual NBA referees to ref the game and Los Angeles Lakers cheerleaders to support the teams. A few NBA legends who couldn't make the game -- Kobe Bryant, Magic Johnson, Carmelo Anthony, Shaquille O'Neal and Scottie Pippen -- sent video messages.
