We're happy to see them cutting loose!

Khloe and Kylie put all their relationship drama with Tristan Thompson and Travis Scott behind them last night, as they celebrated Kylie's personal assistant Victoria's birthday at a roller rink. Kendall and Kourtney also joined in on the fun, but Kimmy K missed out on the occasion.

The LipKit queen and world's youngest billionaire has decided to forgive her rapper beau, after they had a "huge fight" when she suspected he was cheating. The Good American founder, however, has given her NBA player baby daddy the heave-ho.

"Khloe is getting better with every day that passes. Khloe and Tristan are still communicating and always will. Khloe is very big about 'I’m having the father of her child staying in her life no matter how bad things get.' They aren't getting back together and Khloe knows she needs to move on," a source dished to ET.

"It’s been hard for her to realize that, but she knows it’s for the best. Khloe is strong, but she’s really leaning on her family and friends during this time. She’s been spending a lot of time with her sisters and they’ve done a great job keeping her mind off things," the source added.

Who knew Kanye and Scott Disick would be the most trustworthy two of the K clan men?!
