Celebrity Pastor Rich Wilkerson Says Kim Kardashian and Kanye West 'Work Hard' at Their Marriage

Pastor Rich Wilkerson, Jr. officiated Kim Kardashian and Kanye West's wedding nearly two years ago, and tells ET that the famous couple have to work at their marriage like everybody else.

"They're friends of mine and I love them," the Rich in Faith star said of North and Saint West's parents. "I believe in them and I think they've got an amazing, amazing relationship. I think that they work hard to continue to make it happen."

Wilkerson-- who recently released his first book, Sandcastle Kings: Meeting Jesus in a Spiritually Bankrupt World -- doesn't deny that being married has its challenges. "I've been married for nine years and I love my wife [DawnChere Wilkerson] -- and it takes a lot of work for a good marriage," he said. "Everyone has got to face those challenges and walk through it and keep going."

The Miami-based minister added, "Marriage takes work. ...It's easy to fall in love and it takes a whole lot of work to stay in love."

The Kardashian family saw just how hard relationships can be when Kourtney Kardashian broke up with Scott Disick, her longtime boyfriend and father of her three children, over the summer. Wilkerson is also close with the oldest Kardashian sister and told ET that he's optimistic about what the future holds for the former couple.

"They're both amazing friends of mine and special, special people," he said. "They're doing good, you know? They're gonna do good."

The 31-year-old pastor also got to know Kardashian family friend, Justin Bieber, and told ET that he's "the most talented person" he knows. "He's got a heart of gold," he said of the 21-year-old pop star.
