If anyone knows how to throw a killer birthday party, it's the Kardashian family.

The whole crew got together over the weekend to celebrate Khloé Kardashian's 33rd birthday a few days in advance, and it was a surprise affair. The birthday girl had no clue it was happening, but that wasn't even the best part.

Amidst the balloons and the birthday treats, there were five adorable moments that stood out from the rest.

1. Every single one of Khloé's sisters made it to her party.

To say the Kardashians are a busy family is an understatement. For Khloé's birthday though, Kim Kardashian West, Kylie Jenner, Kendall Jenner, and Kourtney Kardashian reunited with Khloé for the fun, making it extra special.

2. She had giant balloons with her name on them.

What's a birthday party without balloons? Khloé and her friends posed in front of the enormous "Koko" letters throughout the night.

3. The Kardashians took advantage of the photo booth.

It wouldn't be a Kardashian party without a photo booth. The sisters took turns posing and took some silly snaps.

4. Khloé looked totally shocked when the surprise party reveal happened.

Each of the Kardashian sisters recorded the moment that Khloé walked through the door, only to be surprised by a huge crowd of her friends and family. What a sweet moment.

5. Her boyfriend and best friends were there supporting her.

Khloé's sisters weren't the only ones who turned up for her party. The star's boyfriend and basketball player Tristan Thompson and Khloé's best friends also came to celebrate her, and they took some of the cutest pictures of the night while they were at it.
