Despite testifying earlier that day against her alleged stalker, Kendall Jenner mixed and mingled with a slew of celebs at the What Goes Around Comes Around in Los Angeles on Thursday night.

Not many things can stop a member of the Kardashian/Kenner clan when they've got an appearance on the books!

Kendall chatted with Rachel Zoe at the opening of the high-end vintage boutique. For the soiree, Jenner sported a Slayer tank top with "Reign" printed on the back, velvet pants and red platform heels. After hitting up the party, Kendall stopped at Hollywood's newest hotspot, Catch, for dinner. Oh la la!

But Kendall wasn't the only celeb who hit up the bash -- Rashida Jones, Crystal Reed, Milla Jovovich, Markus Molinari Ashlee Simpson, Evan Ross and KeKe Palmer all made sure to stop by and check out the not-to-be-missed party!

Meanwhile, earlier in the day things were a bit more serious for Kendall, when she testified in court against Shavaughn McKenzie, who was arrested for trespassing and misdemeanor stalking outside of her home in August.

"I’ve never been so scared in my life,” Jenner told the jury. "I was terrified. I was literally traumatized. It's definitely put me even more on edge. I definitely don't feel safe in my own house anymore." She revealed that she stayed with a friend for some time after that, as she didn't want to be alone in her own home.

Aww! It's hard to be a Jenner/Kardashian!
