It's getting ugly!

On Wednesday the news broke that Amber Rose and hubby Wiz Khalifa were getting divorced after 14 months of marriage, on Thursday she accused him of cheating, and now the rapper has fired back and challenged her move to get full custody of their one-year-old son Sebastian Thomaz.

Amber asked for full custody of their little boy, but on Friday he filed legal documents asking for joint custody. While things could get bitter as far as their child is concerned, Wiz will be paying Amber spousal support (reportedly $5,000 a month) and according to the terms of their prenuptial agreement, she will also be getting a lump sum payment of about $1 million.

What's next with these two? Will it get even nastier or will they change their mind and reconcile?
