The couple wed in 2013, but the model filed for divorce from the Black and Yellow rapper the following year. According to TMZ.com, Amber is entitled to a $1 million (£690,000) hand-out after signing a prenuptial agreement.
The 28-year-old has already reportedly paid Rose $356,000 (£245,000) of the balance.
Under their new agreement, Amber will receive $14,800 (£10,200) in child support for the former couple's three-year-old son Sebastian, while both will share legal and physical custody.
Wiz will also keep possession of the pair's Pennsylvania home and 10 cars.
Following the settlement, Amber and Wiz went to the Ace of Diamonds club in West Hollywood, California together on Monday (06Jun16). The two have remained amicable following an initial public spat and earlier this year (16) Rose opened up about her feelings for Khalifa, calling him her only true love.
"Real love? Was with my husband Khalifa," she said in an interview with podcast Guys We F**ked in January (16). "My soon-to-be ex-husband. Absolutely, for sure. When you really find love, you just know. So you look back at your past relationships and go, 'Eh, I didn't love those fools'. He was the love of my life. He was the only man I've ever loved."
"We obviously loved each other so much, and we still love each other," she added. "Even when we talk on the phone now it's always like, 'OK, babe, see you later. I love you.' We just can't be together. We aren't good in a relationship."
Rose also dated Kanye West from 2008 to 2010.
