Photos taken of the pair show Amber and Wiz counting out dollar bills at the Ace of Spades and then throwing them out into the crowd, lavishly at scantily clad dancers.
Amber also took to Twitter to express her satisfaction at the outcome of their divorce in which she received $1 million as stipulated in the couple's prenup along with $14,800-a-month in child support for Sebastian, her three-year-old son with Wiz.
The pair agreed to share legal and physical custody of their child,TMZ reported.
Wiz got to keep a five-bedroom, four-bath home on 2.8 acres of wooded property in Pennsylvania and 10 cars, including a Porsche, a 1968 Camaro and a 1969 Chevelle.
According to TMZ, Amber already got $356,000 from Wiz and will likely get the remaining $644,000 soon.
The couple married on June 8, 2013 but Amber filed for divorce on September 22, 2014, citing irreconcilable differences.
Initially Amber sought full custody of Sebastian but she and Wiz have shared joint custody since 2015 and have clearly come to a mutually-satisfactory arrangement regarding his welfare going forward.
Amber has previously revealed she and Wiz were working on maintaining a friendship for the sake of their little boy.
'I think that we just wanted different things in our lives,' she said on Larry King Now. 'Being married in the public is not easy. Having access to pretty much any and everything we want is not easy. We still love each other.'
'Right now we're just working on co-parenting and learning how to be friends. He's at my house a lot for the baby. I'm at his house.'
