Model Gigi Hadid celebrated her 21st birthday with a bang Thursday night in Hollywood.
Hadid was joined for a party at celeb hot spot The Nice Guy by her close friends Taylor Swift, Kendall Jenner, and Lily Aldridge. Khloé and Kourtney Kardashian also attended the birthday celebration, along with Ashlee Simpson, Evan Ross, Hailey Baldwin, Jayden Smith, and sister rockers Haim.
Taylor's ex John Mayer was also seen at the party, but it is unknown if they ran into each other.
The party did not have just famous stars; Gigi also invited some of high school friends. In one pic of Taylor from the party, Gigi captioned, "When high school and post-high-school BFF's are united."

Gigi’s boyfriend Zayn Malik was also present at the party, but made sure to celebrate her birthday last weekend, on her actual birthday (April 23). A source told E! News, "Zayn showered Gigi with flowers and presents for her birthday. He was very thoughtful with what presents he got her. Gigi really wanted to see Zayn on her special day and he made it happen. They had a few hours of alone time."
