Kim Kardashian turns 33, but her big party, at Tao in Las Vegas, isn't until Friday.

Who's likely to be in attendance? Well, she rang in the big 3-0 with another bash in Vegas attended by her sisters, Kourtney Kardashian and Khloe Kardashian Odom, her mom, Kris Jenner, and friends Kelly Rowland and La La Anthony.

The next year, she blew out her candles at Marquee in Sin City alongside then-beau Kris Humphries. And last year, her boyfriend, Kanye West, whisked her away to Rome.

So, who is likely to be at her party this year?

Naturally, her family will be in attendance, and best pals Anthony, Rowland, Brittny Gastineau and Ciara are never far away. Kardashian is also very close with fellow reality star Larsa Pippen, as well as publicist Jonathan Cheban, TV producer Carla DiBello, makeup artist Joyce Bonelli and designer Rachel Roy.

Unfortunately, pal Beyoncé is out of the country as part of her tour, but when Kim and Kanye welcomed baby North, she was sure to say congratulations online. Maybe a happy birthday wish will follow?

And speaking of West, he's in the middle of a tour, too , but he didn't schedule a show for the 21st. Maybe the plan is to be with his love?
