Despite being divorced for more than 3 years, Wiz Khalifa’s ex, Amber Rose, is still taking flack. But it isn’t from the famed hip hop rapper - it’s coming from his mother.

Rose is seeking a restraining order against her ex-mother-in-law, Katie Wimbush-Pole, Khalifa’s mother and grandmother to their young son. The move is the latest in a string of legal battles between the pair following the 2014 divorce, however, this time Amber is furious according to sources speaking with TMZ.

Ever since her break-up with Khalifa, the two had a cantankerous relationship at best. Just recently, Wimbush-Pole sued Rose for defamation, claiming Rose accused her of being an unfit grandmother after the recent death of her son and Khalifa’s brother, Dorien. Dorien died due to complications with lymphoma in February.

Before that, the Washington Observer-Reporter ran a story saying that Katie allegedly contacted California Child Services and reported Rose as an unfit parent. Child Services did visit Rose’s home in June, but nothing came of the visit. This sparked another angry and profanity-laden phone call between the pair. Now it seems that Rose has had enough, and is asking the courts to step in.

Sources close to Rose said she believes the feud all stems from the 2014 divorce, which Wimbush-Pole has never been able to let go. The breakup was apparently a difficult one, with Rose seeking full custody of their 4-year-old son, Sebastien. As of 2015, the pair has joint custody, with Khalifa paying child support.

Rose believes the current defamation lawsuit brought against her is all revenge for the breakup. Sources also say she is seeking to ensure the court places a distance restriction on Wimbush-Pole with Sebastien, evidently concerned that Khalifa's mother's hatred for her will affect her relationship with her son.

To that end, she’ll have a lot of evidence in court. Wimbush-Pole has repeatedly attacked Rose on social media since 2014, at one point coming to the defense of the Kardashians after Rose sparked a feud with the famous family. Khalifa's mother is a frequent tweeter, with nary a week that goes by without some mention of Amber Rose.
