When we last saw Gigi Hadid, the model was starring in the video for Calvin Harris' summer smash, "How Deep is Your Love?" The blonde bombshell is currently dating dreamboat JoBro Joe Jonas, and it appears her personal life truly is as glamorous as that vid lead us to believe.

For her bf's 25th birthday, the It Girl totally surprised the guy with what appears to be a sports-tastic b-day bash. All his buds attended, and they're all pretty A-list.

His baby bro Nick Jonas was there with rumored fling Kendall Jenner, as was Joe's former love-turned-friend Taylor Swift. Homegirl even rapped along to Kendrick Lamar's "Backseat Freestyle" in what appears to be a party bus. It wasn't even her event and she still found a way to totally dominate!

Watch that here and another clip from the event above. Then click through a few behind-the-scenes "Bad Blood" vids, which include our leading lady Hadid.
