Priscilla To ‘Drama Queen’ Lisa Marie: Clean Up Your Act Or Else!

RadarOnline.com has exclusively learned that Michael Lockwood isn’t the only one locked in a bitter battle of words with Lisa Marie Presley!

According to an insider, Presley’s mom, Priscilla, is on the rampage after she was forced to take temporary custody of 8-year-old granddaughters, twins Harper and Finley.

“Lisa Marie is just horrible and Priscilla is pissed off at her for doing all this,” sniped the source, calling Elvis’ daughter “such a drama queen.”

As RadarOnline.com reported, the twins were put into Priscilla’s care after what the 71-year-old star deemed the “commotion” surrounding her daughter’s accusations that Lockwood had “hundreds” of inappropriate photos stored on his computer.

“What Lisa Marie’s putting the girls through and stuff is terrible,” scoffed the source, “and it’s all her own doing.”

“She was so screwed up on drugs and every time we tried to help she would threaten to divorce Mike,” added the source, who insisted the seedy accusations 49-year-old Presley lobbed at her former spouse were “all lies.”

On Feb. 22, Presley and Lockwood, 55, squared off in divorce court, where, in the latest chapter in their ongoing bitter split saga, his attorneys requested legal costs and monthly support of $40,000. Lockwood’s lawyer argued that Presley had lied about her income.

The two will next appear before a judge on Mar. 1 for a custody hearing concerning the fate of their daughters.
