Aspiring model Kendall Jenner and sister Kylie took the red carpet at the 2014 Billboard Music Awards by storm on Sunday night, hanging out with some of music's biggest stars, like Jennifer Lopez, Robin Thicke, Ricky Martin and Shania Twain. See them and more stars, including more photos from Cannes and pics from the Nautica Oceana Beach House Party, hosted by Miranda Cosgrove. And a giant stuffed dolphin.

Back to Billboard... Kendall got some practice for her upcoming stint co-hosting the 2014 MuchMusic Video Awards with sister Kylie at Sunday night's Billboard Awards, but she nearly introduced Australian band 5 Seconds of Summer as One Direction.

The 18-year-old flubbed her lines at the event, nearly calling the band One Direction in the process after a strong start. Perhaps the script had something to do with the mix up.

"The band about to rock the Billboard Awards comes from Down Under, but the direction they are heading is straight up," she said. "Recently, they made their debut on the Billboard 200 number two. This summer... and now we welcome, One... Guys, I’m the worst reader.

"Um... They’re only getting bigger! Take a look."

Kim Kardashian's little sister must've also had ex-boyfriend Harry Styles on the brain.

She tweeted afterward that she was nervous and wasn't wearing her contact lenses. "#NeverLeavinMyContactsAtHomeAgain," she hash-tagged the post.

Don't worry Kendall, we don't find them very memorable either.
