Yolanda Foster is one lucky fifth wheel.

In honor of daughter Bella Hadid’s 19th birthday Friday, Foster went to lunch in New York City with Bella, older daughter Gigi Hadid, Bella’s boyfriend the Weeknd and Gigi’s current flame Joe Jonas.

The whole crew kept it casual: Bella wore jeans and a white knit sweater while Gigi paired her own jeans with a hoodie sweatshirt and sneakers. Both Jonas and the Weeknd wore jackets over black pants. Gigi held Jonas’ hand for a while, but also spent some quality time walking with her mom.

Gigi and Foster posted adorable throwback photos on Instagram on Friday to celebrate Bella’s big day. Gigi shared a picture of her as a baby peeking into Bella’s crib and wrote, “You are so special, and your heart is even more beautiful than your squishy cheeeeks (which is hard to beat).”

The proud mom’s pic shows her cuddling with a toddler-sized Bella. The caption includes, “Thank you for blessing my life with your love, kindness and compassion.”

The Real Housewives of Beverly Hills star also posted another picture Friday night showing a smiling Bella, with her mom on one side and the Weeknd on the other, preparing to blow out the candles on a birthday cake.

Friday’s outing occurred just after Foster revealed at Thursday night’s Global Lyme Alliance inaugural gala that her son Anwar and Bella both suffer from chronic Lyme disease.
