The allegations are horrific and ugly, and Gilbert Arenas is laughing.

The former NBA headcase, more known for a gun altercation in the Wizards locker room than his three All-Star Games, has been hit with a restraining order by a former girlfriend, who alleged he has blackmailed her by threatening to send explicit pictures and videos of her to her 10-year-old son.

The woman obtained the temporary warrant through L.A. County Superior Court, TMZ Sports reported. She reportedly had been in an on-and-off relationship with Arenas since 2016, but recently tried to break up for good.

And she says Arenas has exploded.

“Gilbert told me he was watching me at [my] son’s school and that he had just saw him go into class,” she wrote in documents the gossip site obtained.

“He said he was waiting to get my son’s cell phone number from his son so that he could send my child naked photos of me and video of Gilbert and I having sex and video of me naked.”

The allegations get nastier. In the documents, the woman alleges on May 23, Arenas pushed her against the wall and demanded sex. According to TMZ, she fearfully obliged.

After the report emerged, Arenas, the 36-year-old from Los Angeles who last played in the NBA in the 2011-12 season, sent an Instagram message that was filled with laughing emojis.

“Which one of u funky bitches lying on me?😂😂😂😂,” he wrote. “99% of u hoes couldnt get me too call u back after I hit now Someone wants a restraining on me ??🤣🤣🤣.”

Part of Arenas’ explanation appears to be that this woman wouldn’t turn him down.

“[L]isten I know my d–k is like crack but don’t play yea self…like I’m bothering one of y’all 😂😂 TMZ #fakenews,” he wrote.
