Pregnant Kim Kardashian is jetting to Las Vegas where she is hosting a party to ring in the New Year and will be joined by Kanye West

Kim Kardashian is set to ring in the New Year in Las Vegas.

The reality TV star – whose boyfriend Kanye West of eight months announced she is expecting their first baby during a performance at Revel in Atlantic City, New Jersey on Sunday night (30.12.12) – is hosting a party at 1 Oak nightclub in the Mirage hotel tonight and will be joined by the ‘Otis’ rapper.

A source close to the 32-year-old ‘Keeping Up With The Kardashians’ star told gossip website TMZ.com that she has inked a six figure deal to appear at the event.

The insider also insisted that Kim would have no problem avoiding alcohol at the bash because she has never been a big drinker anyway.

Tickets to the star-studded event reportedly cost $125 for standing room, while tables cost $3,000.

Kim has hosted parties in Las Vegas for several years on New Year’s Eve.

The event will mark the couple’s first public appearance together since Kanye, 35, announced she is pregnant on stage at his concert last night, which has since been confirmed by her spokesperson.

During the show, Kanye – who has been dating Kim since April 2011 – told the audience to “stop the music and make noise for my baby mama.”

While Kim – who is believed to be around 12 weeks pregnant – hasn’t spoken about her pregnancy, her family is delighted by the news.

Sister Kourtney Kardashian – who has two children, three-year-old Mason and five-month-old Penelope, with partner Scott Disick – tweeted: “Been wanting to shout from the rooftops with joy and now I can! Another angel to welcome to our family. Overwhelmed with excitement! (sic)”

Sibling Khloe Kardashian added: “Keeping secrets is hard with so many family members! Especially when you are so freaking excited!!!!! LOVE is everything!!!! (sic)”.
