The rapper turned 36 on Saturday night with a star-studded party in NYC, where Jay-Z, Beyonce and Scott Disick helped him celebrate.
And on Sunday night, he closed out the Governor's Ball music festival, which was a three-day weekend event that was dampened by tropical storm Andrea.
Some New Yorkers braved the torrential downpour on Friday to attend the fest on Randall's Island, but headlining acts Kings of Leon and Pretty Lights were unable to perform due to the heavy rains and wind.
Kings of Leon played on Saturday night instead and Guns N' Roses closed out the night. The rockers played their classic hit "Sweet Child of Mine" and covered Pink Floyd's "We Don't Need No Education." Their show featured fireworks and a confetti shower on the crowd at the conclusion.
Kim Kardashian couldn't attend Governor's Ball or Kanye's birthday bash, since she's in the final month of her pregnancy and is no longer allowed to fly.
Update: Kanye played lots of new music from his upcoming album "Yeezus" during his Sunday show, opening and closing his set with "Black Skinhead". He also played hits such as "Jesus Walks," "Runaway" and "Flashing Lights."
It doesn't seem like Yeezy is concerned about whether his new music will get airplay. "When I listen to radio, that ain't where I want to be no more," he told the crowd. "I don't give a f**ck about outside opinions."
