The couple announced the happy news in their respective social media accounts on January 8, 2021.
They shared more details about Nikka's pregnancy journey on their YouTube channel.
Patrick said in the vlog, "Siguro sa lahat ng naging pregnancies niya, parang feeling ko, dito siya pinakanachallenge ngayon."
Nikka threw in, "Yes. Actually, compared to the rest, parang iba. Iba iyong nausea ko dito. Iba iyong food aversions... I'm a little bit challenged, but I know that as I go further into my pregnancy it will get better."
Patrick added that Nikka's pregnancy puts her at "high risk" for coronovirus so they will be staying home to be safe.
Their mom's pregnancy is an "answered prayer" for Michelle, Patrice, and Pia.
The three Garcia girls have been praying for another sibling.
In their announcement vlog, Patrick and Nikka first told the news to their eldest daughter, seven-year-old Michelle.
Michelle was thrilled and even wished her mom to have twins or or triplets.
Patrice and Pia were just as excited as their Ate Michelle about the news.
Patrice is four years old, while Pia is three years old.
Patrick and Nikka said boy or girl, their only prayer is for their fourth child to be born healthy.
