Kim Kardashian's birthday party clashes with a Kanye West concert.

The reality TV star - who turns 33 on October 21 charges guests to meet her at the annual bash, but fans also have the option of watching her boyfriend at a gig on Friday (25.10.13).

Kim - who gave birth to the couple's first daughter North in June - will host the party in Las Vegas while Kanye entertains a crowd at the MGM Grand Garden Arena.

According to, paid appearances for her birthday have always been a good money maker for Kim, whose rapper partner has recently been getting more control over her life.

Indeed, it was reported the 36-year-old star has banned his girlfriend from having cosmetic surgery after his mother Donda died following complications from a similar procedure.

A source previously said: ''Kim was certain that she wanted to have surgery after giving birth because she wanted a head start on losing her baby weight.

''Kanye told Kim in no uncertain terms that she needed to put her baby and her life first.

''He got pretty emotional because he really didn't want her going through that kind of major surgery. He's still traumatised from his mum's death.''
