Khloe definitely partied the night away just hours before KimYe was set to say 'I Do,' but she had to pay for it the next morning.

In a clip Khloe can barely get into the van. It's so bad someone has to tell her to take a seat. She's obviously not in the best mood as she tells her mom, Kris Jenner, and Kourtney Kardashian to "Shut the f*** up."

Khloe ends up revealing to cameras, "We just touched down in Florence. We are trying to get to our hotel and I am so hungover. So trying to race and get ready for Kim's wedding is torture at this point. I just feel like I'm holding back from trying to throw up."

But Kim seemed to be more concerned with her younger sister Kylie Jenner's blue hair than Khloe's state of being hungover. She made it clear that she didn't want Kylie rocking blue tresses when she stood next to her at the altar as a bridesmaid.

"Let's talk the blue hair. I gotta be honest. Are you gonna get clip-ins in it or something to make it not blue?"

While Kylie reassured Kim she had a plan to cover up the blue hair, Kim still had an issue with it.

She confessed to cameras, "I can't stop staring at her blue hair. Like,why does she have to have blue hair at my wedding?"

They suggested that Kylie get extensions and use spray to cover up any blue that still shows.
