Yolanda Foster is making her split official.

The “Real Housewives of Beverly Hills” star filed divorce documents this week to end her 4-year marriage to David Fosteraccording to People.

She cited irreconcilable differences as the reason for the split and is asking for spousal support and legal fees.

The couple announced their breakup in December, saying, “We’ve shared 9 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.”

Soon after, Page Six exclusively revealed that fame was a major cause of their crumbling marriage.

    “David likes to stay relevant. He’s had success and was a big deal . . . so I think [the show made him] feel like he doesn’t hold the same place in pop culture. Maybe it’s a reality check because her daughters are pop culture,” an industry source told Page Six, adding, “I’m sure he’s upset her kids’ careers are popping off and his aren’t. He’s competitive in that way.”

    The Fosters have no children together, but Yolanda, 52, has three kids from a previous marriage: Gigi, 20, Bella, 19, and Anwar, 16. David, 66, has five daughters from previous relationships.

    A rep did not immediately return a request for comment.
