Kendall Jenner has started a bidding war between nightclubs in Las Vegas over which establishment will host her 21st birthday party.

The 'Keeping Up With the Kardashians' star is set to reach the milestone age on November 4 and owners of some of the top bars in Sin City have already laid down $1million in the hope of securing the deal.

An insider told the New York Post newspaper's Page Six column: ''She is the biggest 21st birthday 'get' since Justin Bieber -- and the money's [$1million is] already at Bieber levels.''

Justin threw his 21st birthday bash at the Omnia nightclub in Las Vegas last year, but bar owners are determined to pull out all the stops for the beautiful model as they know her glamorous girl friends Gigi Hadid and Hailey Baldwin will also be in attendance and will likely document the night on their social networking sites and Snapchat accounts.

Kendall's birthday will no doubt be a night to remember if her family - including mother Kris Jenner and half-sisters Kim Kardashian West, Kourtney Kardashian and Khloe Kardashian - have anything to do with it as they are notorious for splashing the cash when it comes to special occasions.

The famous family made sure no expenses were spared when they arranged a lively bash for Kendall's sister Kylie Jenner at the Nice Guy in Los Angeles in August in celebration of her 19th birthday.

It's not yet known whether Kendall's father Caitlyn Jenner - previously known as Bruce Jenner prior to her gender transition surgery last year - will attend her party, or whether she'll arrange another celebration for the brunette beauty closer to her home in Malibu.
