KELIS STROLL'S OUT WITH HER $1,000 STROLLER! MONEY WELL SPENT!

After giving birth nearly three weeks ago, pink weaved new mom Kelis was spotted out with her son, Knight Jones, in NYC this weekend. Last month, a judge ruled Kelis' estranged husband Nas must pay her $55,000 a month in spousal and child support -- which Kelis probably used to buy her nearly $1,000 stroller.
