Alexis Miller, an Atlanta hip-hop artist who goes by MaryJane, just got a restraining order against Shaquille O'Neal, alleging he threatened to hurt her and harassed her with heavy-breathing over the phone, according to TMZ.

The docs claim following their break-up last month, Shaq "threatened to 'blackball" [her] from the recording industry by paying established artists....$50,000 each for their agreement to refuse to perform or record with her in the future..."

According to court docs Shaq wrote her one email that reads, "I dnt no who the fuk u think u dealin wit u will neva be heard from one phone call is all I gotta make no try me. Sho me."

The docs also allege Shaq sent her "an unsolicited vulgar and offensive illustration of a man physically restraining a woman while forcing her to engage in sexual intercourse with him."

O'Neal is scheduled to appear before a judge on Sept. 4.

She claims their relationship ended on July 18.

That's probably not syncing up with Shaq's wife Shaunie, who was photo'd out with him during the July 4th weekend, supposedly working on a reconciliation.

Shaq filed for divorce almost a year ago but the proceeding was put on ice recently because they were supposedly back together.
