Primo Arellano breaks news to dad Drew that Iya Villania’s pregnant with Baby No. 4

Instead of Iya Villania breaking the pregnancy news to husband Drew Arellano, it was their eldest son Primo who told him about the good news that they’re about to become a family of six!

In the YouTube video called “Primo’s Lil Secret Revealed,” Iya and Primo were seen whispering about their plan to tell Drew during their camping trip in Tanay.

According to Iya, her four-year-old has already known about the pregnancy for nearly a week when the video was taken. And while they had planned to keep it until their vacation, it’s been quite hard for Iya to stay mum.

“It’s been a little hard this time around. Medyo nag-struggle na ‘ko to keep it a secret because morning sickness has not been good,” she said. “Things that I used to like, ‘di ko na masyado type.”

Finally when they reached their destination after a long walk, Primo excitedly told the news to Drew who looked quite taken aback, but also excited and full of bliss.

“Mama has a baby, but it’s only very very tiny. It will grow,” Primo blurted out while facing his dad.

After a while, Drew faced Iya, gave her a kiss, and said while smiling: “Ginusto natin ‘to.”

“Because it’s already so hectic with three [children] having to walk in mud, and because we want it to be more intense, we’re gonna add to the family,” Iya said.

They also announced the news to Iya’s mom, who wished that Baby No. 4 will be a girl for her birthday.

Drew and Iya tied the knot in 2014. Together, they have three children: Primo, Leon, and their única hija Alana, who will be an ate soon.

On "Mars Pa More" Monday, Iya shared the news to the public. — LA, GMA News
