Bella Hadid Shows Off Hot Tennis Outfit, Big Racket at French Open

Bella Hadid had the right sized uniform, but oversized equipment, as she took in some French Open action.

Bella rocked a miniskirt in her tight white Nike tennis outfit Saturday at Roland Garros Stadium while watching the Women's Singles Final. Jelena Ostapenko staged a huge comeback to beat Simona Halep.

Serena Williams didn't compete this year -- she's a little bit pregnant in case you haven't heard -- but was on hand to watch this week ... along with celebs like Lindsey Vonn, Hugh Grant, Alexander Skarsgard and Andre Agassi.
