Alex Jazz, the son of Jennylyn Mercado and Patrick Garcia, celebrated his 15th birthday on Thursday, August 17.

In an Instagram post, Jennylyn marked her son’s birthday by sharing a photo of Alex Jazz smiling while holding a birthday cake.

“Another year older, but still the same handsome baby boy of mine!” she wrote. “Happy birthday, Jazzy boy! I love you so much!”

Jennylyn, 36, was a single mother to Alex Jazz before she and husband Dennis Trillo tied the knot last on November 25, 2021, after spending more than seven years together.

The couple also welcomed their first child together — a daughter named Dylan Jade — in April 2022.

In a recent cover story interview for Modern Parenting, Dennis — who also has a son from a previous relationship — and Jennylyn opened up about their blended family.

“Hindi na nila kailangan mag-isip ng iba,” Dennis said. “A blended family is like a regular and normal family. May mga ibang normal family pero medyo dysfunctional sila. Sa amin, kahit blended kami at modern ang setup, we see to it na masaya ang bawat isa and talagang solid kahit ano pang tawag diyan.”

Meanwhile, Jennylyn said she made motherhood her no. 1 priority after giving birth to her daughter with Dennis.

“Mas binibigyan ko pa ng time yung motherhood, si Dylan, and ‘yung family,” she said.

“Nung first time ko magkaroon ng baby, si Jazz, hindi ko masyadong na-enjoy yung motherhood kasi parang two months pa lang, kailangan ko bumalik sa work. So this time, sabi ko hindi ko pwede gawin iyon ulit. Kailangan ko muna mag-focus sa motherhood,” she added.
