To commemorate the occasion, the couple went on a ~relaxing~ trip to Amanpulo with their little bundle of joy, Baby Amari.
"How we spent our 4th wedding anniv," Coleen captioned her post, featuring snaps of them enjoying their vacay. "Our hearts are so, so full!"
Aside from her cute pics with her fam, the actress also shared a series of bikini OOTDs, wowing everyone with her hard-earned fit bod—not to mention her toned abs!
"Yung nakakahiya tabihan ang asawa dahil walang wala ako nyan," Billy commented. "You worked so hard and I’m so proud of you, sacrificing and continuously working hard to achieve the body you want! Na damay na nga ako sa lagree mo eh! But again you look amazing Mommy. Love you so so much! BRAVO My everything." Aww!
In another post where Coleen donned a sultry blue two-piece swimsuit, Billy proudly wrote: "DAS MINE!!!"
Meanwhile, fellow celebs Iya Villania, Pauleen Luna, Jessy Mendiola, and more also flooded the comments section with compliments:
The first-time mom previously opened up about loving and accepting her post-pregnancy body in an Instagram post. She wrote, "I may not be as fit, and I will never be as young, as I used to be. I’m able to point out even more of my flaws now, but I’ve never appreciated myself as much as I do today. I’m at my most beautiful, not because I look it, but because I finally feel it."
