READ: KC Concepcion and Frankie Pangilinan's tribute to mom Sharon Cuneta

As megastar Sharon Cuneta turned 54 yesterday, January 6, her daughters KC Concepcion and Frankie Pangilinan wrote touching tributes on Instagram.

KC posted a throwback picture of her and her mom, probably set in the '90s, with a short but sweet caption.

She wrote, “We may not be perfect, but in many ways I know how to LOVE you, I have, I do, and I always will.

“I have done all I can to help you when I could and to make you proud knowing you had me so young. If I fail, I'm only human and I'm sorry. But I try my best.

“Happiest birthday to you, Mama. May your light shine brighter and brighter and I will see you soon. I love you and pray for your happiness always.”

Meanwhile, Frankie Pangilinan shared a photo of a very young Sharon Cuneta with the caption: “Fifty-four is nothing when your magic is timeless and infinite.

“Happy birthday to Beco's babe, expert vehicular makeup artist, meatloaf connoisseur, record-holder for world's longest pitstop, boy pablo enthusiast, professional book wrapper, monique, emmy, dorina, darna - my best friend. I love you more (promise).”

Happy birthday, Sharon!
