Veteran actor Aga Muhlach is embracing his role as a doting grandfather, sharing a fun-filled bonding experience with his grandkids.

His eldest son, Luigi Muhlach, whom Aga shares with actress Janice de Belen, took to social media to share glimpses of their family time.

On Instagram, Luigi posted a video of Aga enjoying a jet ski ride with his grandchildren Alejandro, Adriana, Anya, and Ariella, each taking turns riding along with him.

"Lolo duties," Luigi captioned the post, adding laughing emojis to highlight the lighthearted moment.

Expressing his gratitude, Luigi also shared how much his children enjoyed spending time with their grandfather.

"The kids had the best time of their lives with you @agamuhlach317 @itsmecharleneg," he wrote, tagging Aga and his wife, Charlene Gonzales.

Aside from Luigi, Aga is also a proud father to twins Atasha and Andres, his children with Charlene, both of whom are now exploring their careers in the entertainment industry.

Meanwhile, Janice de Belen, Aga's former partner, is a mother to four other children — Ina, Moira, Kaila, and Yuan, whom she shares with her ex-husband, John Estrada.

Aga and Janice once formed one of the most iconic love teams in Philippine cinema, starring in classic films such as Isabel Aquino: I Want To Live, Pakasalan Mo Ako, Nasaan Ka Nang Kailangan Kita, The Crazy Professor, and Bakit Madalas Ang Tibok ng Puso.

Their lasting bond as co-parents and now as grandparents continues to bring joy to their growing family.
