Kanye West might be getting too old for late night partying. Don't get me wrong, the 36-year-old "YEEZUS" rapper has been working very hard throughout his career from jetting to Paris several times per month, recording hits in the studio, and selling out numerous concerts and finding the time to drop & promote new albums.

Lets also add being a new dad to four-month-old daughter, North West.
After performing at the MGM Grand Arena in Vegas, Mr. West headed over to club TAO inside The Venetian for his fiancee's 33rd birthday with rapper Tyga and fiancee Blac Chyna, Naya, Scott Disick, Kris Jenner, Jonathan Cheban, Khloe and Kourtney Kardashian. He was also photographed leaned up against a wall sleeping (first photo above).
Kim also revealed last night that she will be taking her rapper beau's last name to E! News:

“Before her party, when asked if she would take the surname West, she dished yes, and that her name would be Kim Kardashian West. Very exciting!”

Adding:

"She also revealed that up until the bended knee moment, she thought she was just having dinner on a baseball field with West. She was in so much shock and was “shaking,” but saved the tears for after the proposal."

FYI: Khloe rocked a Herve Leger dress and Tom Ford boots. Kim wore a Dolce & Gabbana white laced dress (showing off her post-baby body) and gold Tom Ford heels -- all purchased in Paris. Kourtney rocked a black leather dress and zebra-colored heels.
