Who needs a man when you have sisters? Khloé Kardashian (and the rest of the Kardashian Klan) wished Kourtney a very happy 39th birthday on April 18, but Khloé's message seems to have a little extra significance. She just welcomed her first child — daughter True Kardashian — one week ago, after learning one day earlier than boyfriend Tristan Thompson cheated on her. Well, her birthday slideshow for Kourt reminded us that Khloé doesn't need a guy in her life. She's gonna do her with or without Tristan! Watch the video above to see all of the pics and videos.

"Happy birthday @kourtneykardash!!!!" wrote Khloé. "In any lifetime I would have found a way to have you in my life forever! I can’t imagine life without you! Have the best birthday!! You deserve everything and more! Forever and always I love you!!!." What's special about the memories she included is that they're some of the best times in Khloé's life. She's laughing, partying, joking around, looking damn fine, and being her regular fun-loving self. It seems like she's telling Tristan "look, I was the life of the party before you, and I'll be just fine after you!" She also proved that she's more than hot enough to get any guy she wants, because one pic shows her pulling down her yoga pants to reveal incredibly sexy, rock-hard abs. Knowing the Kardashians, it'll be mere months before she's looking like that again. Tristan is already begging for forgiveness, and we can totally see why!

It's sad to think that just one month earlier, Khloé was writing out a similarly sappy post to the man she thought would be her king forever. "To the happiest of birthdays my love!" she captioned a photo of them kissing. "How special is this thing called life that we share together?! I am so blessed to be creating beautiful monumental memories with such a wonderful man! I hope this year brings you all that you dream of! You will forever be my always! I love you baby! ✨." Khloé still hasn't removed the post despite the drama, and her first update since having True makes it seem like she's considering giving him a second chance.

"Our little girl, True Thompson, has completely stolen our hearts and we are overwhelmed with LOVE," she wrote. "Such a blessing to welcome this angel into the family! Mommy and Daddy loooooove you True!" Even if Khloé moves on without Tristan, at least something amazing came out of the relationship. Keep doing you, girl!
