Lea Salonga shared her message for her former onscreen partner Aga Muhlach, who was celebrating his birthday on Monday, August 12.
On Instagram, the Broadway star posted a photo of Aga with her daughter, Nicole Beverly Chien, as she greeted her "friend" on his special day.
"I can't remember what was happening or what these two were talking about, but it looked like fun. Happy 50th, my friend! May it be a beautiful day, wherever you are!" Lea wrote as caption.
Responding to this, Aga wrote: "Thank you!"
Aga and Lea worked together as a love team in hit films "Bakit Labis Kitang Mahal" (1992) and "Sana Maulit Muli" (1995).
Though the two never became real-life lovers, the former matinee idol admitted that he once fell in love with Lea in a touching love letter he wrote for her book, "Playlist -- A Celebration of 35 Years", which went viral in 2017.
"Lea is the one that got away. And she never knew," an excerpt read. "So now she knows. We are older and wiser now, we have gone our own ways, we are no longer the same. But the fire has not ebbed."
"Rather it has grown deeper, stronger, quieter, more enduring. I love her still, but perhaps because she got away, I have her as a friend now, and so I will always have her," he added.
Currently, Lea is married to her non-showbiz husband Robert Charles Chien, while Aga is married to beauty queen-turned-actress Charlene Gonzales.
