Lamar Odom may still be holding on for one more shot with Khloe Kardashian, and that could have led him to "ambush" her outside of a Beverly Hills, Calif., gym.

The former NBA star knows, though, that he could be too late, considering his soon-to-be ex-wife has moved on with current NBA stud James Harden.

"Lamar has been hating that Khloe is with James," an insider told Us Weekly. "Lamar wants her back. That's what stopped the communication on her end."

In an attempt to speak to Khloe, Lamar "blindsided" Khloe outside SoulCycle on Aug. 12 at 6:45 am. "Lamar was demanding that [Khloe] talk to him. She kept walking as he was screaming," an eyewitness told TMZ, who posted a grainy image of the alleged altercation. "At that point Lamar touched Khloe's arm and she screamed at him, 'Get off of me, get off of me. Stop. Stop.'"

How Lamar knew she would be there at that hour of the morning is unknown, leading many media outlets to think he may have followed her.

On Aug. 13, though, a TMZ camera crew caught up with Lamar. In a full-fledged rant, he said "nobody got followed."

"I am not, not, not the person that they're trying to make me out to be -- whoever's doing it. I live in Las Vegas. I live in Las Vegas!" he said. "So, was there an address or a place given? Was there an address or a place given? Or I just guessed right? Did I just guess right?"

Odom angrily instructed the cameraman not to interrupt him or "put words in my mouth."

"Did I just guess right where this girl may be? You know I know Khloe, right? You know I know her, right? So, how would you think I ended up there?"

During his rant, he didn't actually say how he knew where his ex would be. According to People magazine, Lamar has been trying desperately to contact Khloe, so much so that she had to change her phone numbers several weeks ago because he would not stop calling.

"Lamar has been trying to contact Khloe, but she is done and has ignored him," a source said. "Lamar has issues with Khloe dating [James] Harden."

Over the past several months, the "Keeping Up With the Kardashians" star hasn't really hid her blooming romance with the Houston Rockets star. The two were spotted celebrating the Fourth of July together in Las Vegas and they've been spotted all over Los Angeles and even in Hawaii.

The relationship is just not sitting well with Lamar, although he didn't mention James in his rant.

"To everybody I know that supports me I'm sorry but that's just it. The dog has to fight back. That's it. Y'all won. Y'all beat me down, degraded me. You said I would do everything in the world," he said. "I'm a womanizer, a f------ drug addict, everything. You know what I'm saying? I probably couldn't even get f------ hired by Home Depot right now because of how people look at me. It's over! If it happens again I will air everything out."

He continued, "Nobody got followed, nobody got hassled, nobody got harassed, nobody got grabbed on, none of that. None of that. Didn't happen. Probably was the most hurtful part is that I beat her to the punch. I didn't want to come up here. You know what I'm saying? Somebody should be calling up here saying, 'Hell no that didn't happen!" You know what I'm saying? 'That is ridiculous! It's crazy!' I don't now what type of move it is. I don't know. I don't know."

The incident has left Khloe "emotionally shaken" and she's now in the market for a bodyguard, People reports.

"It was a really scary morning. She was totally freaked out, she had no idea how he found her," a source said. "Not only was it a surprise to see him, but it truly was a scary interaction."

"She's such a strong woman, it's crazy to think about what she's gone through. But she was absolutely emotionally shaken from this," the source says. "And the thing is, despite everything that had happened with Lamar, she acknowledges that it overall was a good time in her life and he was a good guy with demons. This is definitely making her reevaluate and move on."
