Ex-husband Kris Humphries has been kind enough to offer a little advice to Kim Kardashian's new man, Kanye West: "Good luck dude, you're going to need it."

He also said that Kanye would need "a lot of patience" to cope with his new girlfriend. Kim and Kanye's relationship became official only a few days ago, but according to a lot of others, including Kris, the pair have been hooking up for the past 2 years.

"Kim kept in touch with Kanye after she married Kris, and promised him that she would cut off communication with him, but she never did," a source told Radar Online.

"Kris knows that while he was with Kim, he was completely faithful, and he has serious doubts that she could say the same thing.

"Kanye is head over heels in love with Kim, and he has told her he would love to appear on the reality show if she wants him to. Watch for Kanye to make several appearances on the show towards the end of the season."
