Kelis is selling her New York City apartment for $2.2 million.

The 'Milkshake' rapper has listed her Campiello Collection pad in the swanky Chelsea district of 'The Big Apple' for immediate sale.

The 1,663-square-foot property comes with two bedroom, two-bathrooms but it has been described by a Sotheby's broker with the listing as a ''work in progress'', according to the New York Post newspaper.

The building it is situated in has a 24-hour doorman and a gym which can be used by all residents.

Kelis - who has a three-year-old son Knight with her ex-husband, rapper Nas - purchased the home in 2005 for $1.3 million.

Nas, 39, and Kelis split in April 2009 while the 33-year-old musician was pregnant with Knight.

The 'I Can' rapper was initially ordered to pay his former wife $45,000-a-month in spousal and child support before having the sum reduced to $25,000-a-month because of money problems.

Nas - who also has an 18-year-old daughter Destiny with former partner Carmen Bryan - branded the sums he was ordered to pay ''crazy''.

He previously said: ''Life is crazy. I wound up paying more money to baby mommas than what some of my rap brothers and sisters make ... (The divorce) put a lot of my business out there, man. People weren't thinking I was making that kind of money, and now they knew.''
