Three certainly isn't a crowd for Gigi Hadid, her boyfriend Joe Jonas and her gal pal Kendall Jenner.
The trio looked to be thoroughly enjoying themselves at the U.S. Open in Queens, New York on Tuesday as they watched Serena Williams defeat her sister, Venus, on the court.
When Gigi wasn't goofing off with Kendall, she was cuddled up to her beau Joe. The 26-year-old singer was even seen tenderly kissing his 20-year-old girlfriend on the forehead as she leaned on his shoulder.

The models were quite stylish for the big event. While Joe kept it casual in a printed t-shirt and jeans, Gigi went Western chic with a bright scarf, a denim shirt and skinny jeans.
Kendall went for a sexier style, stepping out in a fuzzy, white crop top and a matching miniskirt.

Joe and Gigi have accumulated quite the squad since getting together earlier this summer. In August, the former boy band member's 26th birthday party had a slew of stars on the guest list, including Joe's ex Taylor Swift, his brother Nick Jonas and Kendall.
