DEBY / AKM-GSIGigi Hadid knows how to throw a party!
The 21-year-old model celebrated her milestone birthday at The Nice Guy in Los Angeles Thursday, and tons of her celebrity friends turned out to support her. Taylor Swift, Hailey Baldwin, Kendall Jenner, Jaden Smith, Kourtney Kardashian, Khloe Kardashian, Lily Aldridge, Ashlee Simpson-Ross, Evan Ross, Shanina Shaik and more stars dressed in red, white or black outfits.
The birthday girl wore a pair of high-waisted white shorts and a silky black camisole that was short in the front but cape length in the back. Gigi paired her outfit with thigh-high boots and a black choker. Her BFF T.Swift channeled the '90s in a one-shouldered sequined dress and showed the world she's keeping her bleached locks.
Gigi's birthday party wasn't only celebrities, though. She brought some of her high school friends who quickly became fast friends with the model's new crowd. She took to Instagram to document one such friend solidifying his new connection with the "Style" songstress.
"When high school and post-high-school BFF's are united," Gigi captioned the pic.
Although all the stars were spotted making their way into the party, the photo fun didn't stop once they got inside. Everyone took to the venue's photo booths to snap some black-and-white images. T. Swift scrunched up next to Aldridge and the three sisters of Haim, her longtime gal pals. It looks like Aldridge stuck around the photo booths because she was also captured in photos with Kourtney and Khloe, as well as Smith.
Gigi also celebrated her birthday last weekend, with a quick trip to Coachella with Calvin Harris and Swift. She also had a birthday brunch at her dad's house with her family and hit up Malibu with boyfriend Zayn Malik and sister Bella Hadid.
"Zayn showered Gigi with flowers and presents for her birthday. He was very thoughtful with what presents he got her," a source told E! News. "Gigi really wanted to see Zayn on her special day and he made it happen. They had a few hours of alone time."
Despite their busy schedules Gigi and Zayn always try to find the time to meet up. "When they are not traveling they are always together," the insider added.
Happy birthday again, Gigi!
