Khloe Kardashian has been left shaken and 'freaked out' after her estranged husband confronted her when she left an exercise class.

The 31-year-old reality star just can’t seem to escape her 35-year-old ex. While heading to her SoulCycle workout class at 6:45 a.m. on Aug. 12, Khloe Kardashian faced a major surprise when Lamar Odom followed her into the parking lot, and a crazy fight reportedly ensued.

According to website TMZ the former NBA star allegedly launched a verbal attack and demanded Khloe to speak to him.

During the alleged ambush, Lamar came out of nowhere and began screaming at his ex. An onlooker said Khloe attempted to ignore him but he grabbed her arm. She allegedly screamed: "Get off of me, get off of me. Stop. Stop."

Another eyewitness is said to have asked Khloe if she wanted the cops called, then Lamar shouted, "You're not going to call the cops on Lamar Odom."

At that point, Khloe Kardashian began fighting back and was even heard asking, “How did you know I was here?!” According to TMZ‘s eyewitness, the 'KUWTK' star was totally freaked out, ran to her car and immediately drove away.

People reported on Wednesday that Khloe had been forced to change her number because her ex wouldn't stop calling her.

Khloe Kardashian has dealt with a lot when it comes to Lamar Odom. She broke up with him and filed for divorce in Dec. 2013 after finding out he cheated on her and allegedly used drugs, but has still been there for him through difficult times ever since. And even though the divorce documents were finally signed on July 17.

It was only on Sunday during Kylie Jenner's 18th birthday that Khloe made her first public debut with her new boyfriend James Harden.

She had been keeping the relationship very much on the down low until the event.
