Kristine Hermosa recently gave birth to their fourth child late last night, November 5.
Sharing this good news was her husband Oyo Sotto who immediately posted a photo of their third biological baby in his Instagram account.
They named him after Oyo's dad and Eat Bulaga! bossing Vic Sotto.
Baby Marvic Valentin is now the bunso of Oyo and Kristine. He has three siblings.
Kuya Kristian Daniel or Kiel Iwas adopted before the couple tied the knot last January 12, 2011.
Tin (Kristine's nickname) then was diagnosed with severe polycystic ovary, a condition in which a woman's hormones are out of balance causing problems with the menstrual cycle, even fertility.
In 2011, the actress learned she was pregnant with her first biological child. Oyo squealed with delight.
But the couple had to seek advice from their pastor to make sure their baby boy wouldn't feel left out.
In an interview then with Philstar.com, Oyo said they "were advised to just make him feel secure and really fill him with love.
"When the right age comes, we have to tell him that he’s adopted and certainly by that time, he will be secured enough by our love not to feel bad."
Kiel has appeared on a TV commercial for a milk product with his mom Kristine.
On December 26, 2011, the celebrity couple welcomed their daughter Ondrea Bliss.
In one of his posts, Oyo described her only daughter as "little miss painter" as she loves to do artworks.
Three years later, Kristine was pregnant again.
He wrote, “When 2014 started, we believed God for so many things… one of those is to have another baby without having to take any medication since Tin has polycystic ovaries.
"And now, God answered one of our prayers to have another baby."
On October 11, 2014, they welcomed their bouncing baby boy, Kaleb Hanns.
According to behindthename.com, his first name means faithful or wholehearted.
Here's a photo Kaleb shortly after he was born:
We can't wait to see photos of these cute chikitings with their baby brother Marvic.
Congrats, Oyo and Tin!
