Wiz Khalifa's wife files to end marriage to rapper

LOS ANGELES, CA -- Model Amber Rose is ending her yearlong marriage to rapper Wiz Khalifa.

Rose filed for divorce on Tuesday in Los Angeles, citing irreconcilable differences. She is seeking custody of their 20-month old son and spousal support as laid out in the former couple's prenuptial agreement.

Court filings state the couple separated on Monday, but provide no other details on the split or how the pair's finances will be divided.

They were married in July 2013 less than five months after their son was born.

Khalifa, whose hit "Black and Yellow" help make his 2011 album "Rolling Papers" a success, released his latest album "Blacc Hollywood" in August.

The divorce filing was first reported Wednesday by celebrity website TMZ.
