Kim's b'day bash clashes with Kanye's gig

It seems socialite Kim Kardashian will have to spend her birthday away from boyfriend Kanye West.

Kim will turn 33 Monday and will host a party in Las Vegas where guests have to pay in order to meet her. But her beau Kanye will have to skip the bash as he would be performing at the MGM Grand Garden Arena in sin city itself, reports radaronline.com.

The couple have a four-month-old daughter North West.
