Another Hollywood marriage has ended with Yolanda Foster and David Foster divorcing after four years of marriage.

The two stars announced their break up on Tuesday, Dec.1, Entertainment Tonight reported. In a joint statement issued by the former Hollywood couple, Yolanda and David stated, "Sadly we have decided to go our separate ways. We've shared nine beautiful and joyous years together. During that time we experienced love, friendship and the inevitable challenges that come with managing a marriage, careers, blended families and health issues."

The couple further mentioned that they were “grateful for the years [that they] spent together,” and commented that they “wholeheartedly” did their best during the relationship. “We hope that we can pave the road ahead of us with all we've learned,” the former couple’s statement continued. “And with the love and respect we will always have for one another.”

The “Real Housewives of Beverly Hills” star married the music legend in a fairy tale wedding in Nov. 2011. At that time, David told Yolanda that he considered himself “the luckiest man on the planet,” according to People magazine.

However, multiple sources told Us Weekly that the reason behind their separation is David’s busy schedule and Yolanda’s ongoing battle with Lyme disease. A source told Us Weekly that Yolanda has “basically been sick” most of the former couple’s married life. The reality star's sickness, coupled with David’s constant travels, has “definitely took a huge toll on the marriage.”

Another insider revealed to Us Weekly that Yolanda has felt her husband’s absence during the tough times when she was battling Lyme disease. “She just felt he wasn’t there for him when she needed him most and he felt the same,” the source stated. “It’s so sad but the illness really did come between them."

Yolanda has three daughters from her first marriage with Mohamed Hadid, namely Gigi, Bella and Anwar. Meanwhile, David has five daughters and has been married four times.
