"Truly beyond grateful," wrote the blogger in her post, which showed a photo of her and Patrick with their baby boy.

"I couldn't contain my tears the minute I heard you cry. I am overwhelmed with so much joy! I have never felt this much in love and I couldn't ask for anything more. You and your ate’s are our answered prayer! We love you more than you will ever know," she said.

Several celebrities quickly congratulated her and Patrick in the comments section of her post, including Jake Ejercito, Kaye Abad, Nikki Gil, Nikki Valdez, Neri Naig, Troy Montero, and Dani Barretto.

It was last January when Patrick and Nikka announced they were expecting their fourth child -- this time a baby boy.

"We can't thank the Lord enough. Sobra sobrang good ng Panginoon," Nikka said in their gender reveal vlog. "This is so personal to me, kasi parang grinant niya talaga 'yung desire ng heart ko."

The couple has three daughters -- Michelle Celeste, 8, Nicola Patrice, 5, and Francisca Pia, 3. Patrick also has a son, 12-year-old Alex Jazz, with former girlfriend Jennylyn Mercado.
