American reality television star Khloe Kardashian is reportedly giving estranged husband Lamar Odom the silent treatment.

According to Radar Online, the 34-year-old professional basketball player has been "blowing up her phone" by making "desperate calls" to Kardashian.

"She's been refusing to take his calls lately," an insider said.

The 29-year-old 'Keeping up With the Kardashians' star has been linked with several men since parting ways with Odom, including rapper French Montana and The Game.

"Khloe is out in public with new guys all over them and it is killing Lamar," the source told the website. "Yeah, he was totally with other women [first], but he doesn't want Khloe to shove it in his face that she is moving on. Lamar is jealous and gets mad when she refuses to talk to him."

Kardashian filed for divorce from Odom in December, after four years of marriage, citing irreconcilable differences. The couple's marriage first hit the rocks when a video surfaced, showing Odom rapping about how he cheated on her. He was also allegedly not willing to take professional help for his drug addiction.

"Lamar has been telling people that they don't have to waste any more time with each other," the insider added. "He wanted to get back with her, he's been blowing up her phone lately, but since she wants nothing to do with him he's saying he's done with her too. He's making a lot of desperate calls."

However, at a press conference, Odom revealed he would like to rebuild the couple's relationship.

"I love my wife. She'll always be my wife, no matter what. Who knows? We don't know exactly if the divorce is going through. Only time will tell. I hope not. But even if we were divorced, she would always be my wife," Odom had said.
