The "I Am Me" singer netted the hefty profit by selling her impressive mansion in Los Angeles' Burbank district for $5.7 million to an unidentified buyer, TMZ.com reported.
Included in the pop star's former home was a 700-square-foot closet with its very own washer and dryer.
There was no information available on why Simpson, the younger sister of pop singer Jessica Simpson, sold the property.
