The teenage E! stars attended Rihanna's concert in Los Angeles last night, and Kendall couldn't hold back her enthusiasm over seeing the "Diamonds" singer live and in person.
"We're like the first ones here!" Kendall said in a Keek video from the Staples Center where Rihanna later performed. "So excited, we're gonna party the night away!"
Throughout the night, Kendall continued to share her excitement on Twitter, tweeting "happy RiRi" with a pic of herself at the concert, and sending out some lyrics from Rihanna's hit "You Da One" as well.
After the concert, Kendall and Kylie could be seen dodging paparazzi as they got into their cars. Kendall departed with a group of friends, while Kylie left in another car driven by none other than rapper Lil Twist!
