Wiz Khalifa has blasted Amber Rose for "using" their son "against" him. Never a nice thing to do or be accused of. 

The 27-year-old rapper branded his estranged wife - who filed for divorce last September amid claims he had cheated on her - a "foul creature", claiming she had "done something" to two-year-old Sebastian to "spite" him.

Responding to a fan who told him to "get your wife back" on Twitter, he initially replied "no thanks" before launching into a tirade.

Wiz - whose real name is Cameron Jibril Thomaz - admitted seeing his little boy always made him feel better.

Following her split from Wiz, 31-year-old Amber insisted Sebastian was her main priority and she wasn't ready to date again.

She said: "I'm focused on my son and my work. I really don't have time for a man. I'm going through a divorce and technically I'm single, but I'm just not ready for [that]."

For those of you on the hunt for an example of Amber Rose's "work". Here's a recent compilation. Amusing title is not artist's own.
