Whitney Bischoff, the winner in season 19 of "The Bachelor," is moving on after her split with Chris Soules. On Sunday, she celebrated her 30th birthday, and she was joined by finalists Kaitlyn Bristowe and Becca Tilley for her special day. 

Bischoff, Tilley, and Bristowe were the final three in Soules' season of "The Bachelor." Although they competed for his heart in season 19 of the show, they were all smiles as they documented their reunion on Instagram. 

Bischoff posted a black and white snap and wrote, "Reunited and it feels so good! @kaitlynbristowe @beccatilley5 #happybirthdaytome."

Tilley also shared a collage of selfies with her former castmates and captioned it, "Chitown- you rule."

Bischoff — who announced in May in a joint statement that she and Soules had ended their six-month engagement — wore a fitted white shirt and a black hat for the outing, while Bristowe donned a knitted grey beanie. Tilley was dressed in a fitted lace top and wore her long hair in loose waves for the picture. 

A week before their split, Bischoff visited Soules at his Iowa farm and even tried her hand at driving a tractor. Soules posted pictures of her visit on Instagram, so it was a surprise for fans when they announced that they were ending their engagement several days later. 

Tilley has recently spoken out in support of Bischoff in an interview with People. 

"People are like, 'Wait, you were her competition'," she said. "When all is said and done, she was my friend and he's such a good guy. I wanted it to be a happy ending, but I think they're both sort of bummed."

Meanwhile, Bristowe, who also turns 30 this week, shared a new picture over the weekend. She captioned a shot of her and Bischoff, "Celebrating our birthdays early today @whitb624 hurry up." 

Bristowe is currently in the process of finding her true love on "The Bachelorette" which airs Mondays at 8 p.m. on ABC.
