Aguilar expressed her gratitude after Mercado greeted Calix on his birthday through an Instagram post. The multi-awarded actress also included photos of the birthday boy who was at a fencing competition.

Awed with the sweet post, Aguilar showed how grateful she is on the comment section.

"Thank you mommy Jen for loving Calix as your own," she said.

Trillo also shared a birthday greeting for his first child on the same platform, with the video of the same fencing match.

"Daisy Siete! Congrats to my panganay, so proud of you, mahal na mahal ka namin! We’re always here for you! Happy Birthday," he wrote.

Calix is the eldest in the blended family of Trillo and Mercado. The Kapuso actress and Aguilar evidently share a healthy relationship over the years, exchanging parenting advice.

"'Pag minsan naiinis ako kay Calix, sinusumbong ko kay Jen actually… Stepmom siya and ‘pag wala ako, siya ‘yung tumatayong ina kapag kasama ni Dennis si Calix," Aguilar mentioned during a 2023 interview.

She has two other younger sons aside from Calix.

Meanwhile, Mercado has a son, Jazz, with Patrick Garcia, and a daughter, Dylan, with Trillo.
