Kim Kardashian Fighting With Kanye West

In the midst of a nasty divorce from Kris Humphries, it seemed as if Kim Kardashian had found a shoulder to lean on and a second chance at love with her longtime friend and sometime flame Kanye West.

The two were in contact during her marriage, as Star has reported, but just when they've finally taken their relationship public, Star has learned there's trouble in paradise.

"Kim and Kanye had their first real fight at the beginning of April," a source tells Star. "Kim is obsessed with money, and it was starting to irritate him how that's all she can talk about."

During a date a NYC's Serafina restaurant and a visit to toy store F.A.O. Schwarz, "She kept asking him about his touring revenue, the properties he owns and his savings," says a source. "Kanye finally had to tell her to back off and chill out. He told her that she has nothing to worry about."
