Celebrity sweethearts Luis Manzano and Jessy Mendiola appear more in love than ever as they celebrated their second anniversary as a couple on Monday.

On Instagram, the two shared photos of them touring Vatican City, one of the stops in their Europe vacation, apparently to mark the milestone in their relationship.

Based on their updates, they've also been to Rome and Paris.

Addressing his "Howhow," Manzano wrote in the caption of a kissing selfie: "Happy 2nd anniversary! Thank you for being the best travel partner, dive buddy (even if nanghahabol ka ng barracuda) and howhow in life.

"I always thank God you went to my birthday party 2 years ago (kahit na ayaw mo naman talaga). I howhow you! Oh, thank you for taking me to Europe."

Since they first went public with their relationship in July 2016, Mendiola and Manzano together have weathered intrigues, in connection with the actor-host's past relationship with actress Angel Locsin.

Time and again, he has denied that his relationships with the two women overlapped, saying he was single for half a year before his relationship with Mendiola became official.
