Amber Rose Files for Divorce from Wiz Khalifa

0924-amber-rose-wiz-doc-gidibaseAmber Rose has filed for divorce from husband-of-1-year Wiz Khalifa … and she’s gunning for full custody of their kid … TMZ has learned.

In the divorce docs — obtained by TMZ — Amber says they split on Monday and cites irreconcilable differences.

Amber is asking for full legal and physical custody of their 1-year-old son Sebastian. She’s willing to give Wiz visitation.

And this is interesting. Amber acknowledges there’s a prenup, which you would think would work in Wiz’s favor, but she says it’s valid … presumably, she’s not challenging it. The docs say the prenup provides spousal support.

As for why they split, there’s been a buzz over the last few days of infidelity, but there’s no mention of it in the papers.
