Bianca De Vera greets Will Ashley on his birthday with throwback photo

Bianca De Vera had a special birthday greeting for Will Ashley on his 23rd birthday.

In an Instagram Story, Bianca shared a throwback photo of herself and Will at a carnival. She held a giant stuffed unicorn, and they both posed with wacky faces.

"Happy birthday, Will Ashley," she wrote.

The pair of Will and Bianca, or "WillCa," was one of the standout ships that emerged from "Pinoy Big Brother: Celebrity Collab Edition."

However, their undeniable chemistry wasn't a recent discovery. Long before their connection was reignited inside Bahay ni Kuya, the spark between them first caught viewers' attention when they starred together in "Unbreak My Heart" two years ago.

While inside Bahay ni Kuya, the pair confessed to having unresolved tension from their "Unbreak My Heart" days.

They previously attended a fund-raising gig in support of animal welfare organized by their fans and attended by OPM artists, some of whom have dedicated their songs to WillCa.
