The `Black and Yellow` rapper has purchased the 3,891 square-foot mansion in Canonsburg, Pennsylvania, which will be the first house for the couple. The luxury property - which is eco-friendly - sits on 2.8 acres out in the country and boasts five bedrooms and four baths. It features Brazilian Kos floors, stainless steal appliances and a lavish master suite as well as a separate guest house. The couple got engaged earlier this year and Wiz took to his twitter account to reveal the model accepted his proposal after more than a year together. In a message accompanied by a picture of the 28-year-old beauty`s engagement ring, he tweeted: "She Said Yes!!! (sic)" Following the announcement, Amber - who famously dated Kanye West - took to her twitter account to express her joy. She wrote: "He has made me the Happiest Woman in the World!!!! (sic)."
