Look at this unbelievable interchange (below), starting with The Donald's initial tweet:
And that was after Justin and Selena went on a vacay to the Caribbean together!
Confused? You should be. All these friendships and relationships sound pretty complicated to us.
However, in a recent turn of events, Cara Delevingne posted a video on Instagram that features both Selena and Kendall, and even has Selena singing Happy Birthday to her!
Well, looks like their feud is officially over. Maybe this was the birthday gift that Kendall wished for today?!
