Sisterly love. In honor of Kourtney Kardashian’s 40th birthday, Khloé Kardashian poked fun at the mom of three by posting some embarrassing videos of her on her Instagram Stories, including one where her mouth looked odd from a dental procedure.

“A tiny clip to appreciate my queen Kourt the day before her birthday,” the 34-year-old captioned the hilarious video which showed Kourtney’s crooked lip on Wednesday, April 17.

In the clip, the Good American designer couldn’t stop laughing. “Kourt. Kourtney, look at me,” she said while the two were at a restaurant together. “What is wrong with your mouth?”

However, the Poosh creator wasn’t having it. “It’s not nice. It’s numb. It’s not nice. Stop. Khloé, it’s rude,” she exclaimed.

Naturally, Khlo couldn’t let it go and kept on bugging her sister about her situation. “What did you do to your mouth? You went to the dentist?” she asked. “Please show my Keekers what you did,” referring to their other sister Kim Kardashian.

The brunette beauty replied, “I didn’t do it. The dentist did it. No, I didn’t have a root canal.” It seems like their interaction was all in good fun as the duo couldn’t stop giggling.

Koko continued to show her sister some more love by posting several other videos and snaps of their adventures on social media. “Happy birthday sweet @kourtneykardash!! I am completely obsessed with each and every one of my siblings,” she said. “Still blows my mind how blessed we are to call each other sisters. You and I haven an incredible rare bond that no matter what, it can never be broken. You’re my best friend, one of the rare few I can count on most in my life. I’m so thankful for that. I know that so many people go through life without their sister as their best friend or without a sister in general, and I don’t know how they do it.”

She added, “Honestly, without you my life would be boring and not as full. Today and every day, I pray that your soul is awakened and from your core, you’re happy! You deserve only magical things for the rest of your life! In all of the lifetimes before and in all of the lifetimes later, I will love you! To the happiest of birthdays my sweet sister!! Jane or Suzanne (I forgot who’s who). I love you!”

Aw, these two are too adorable.
