MANILA -- "I made a big, big mistake."

This was the confession of former "Pinoy Big Brother" housemate Marco Gallo when asked about what happened between him and Kisses Delavin.

In an interview on "Tonight With Boy Abunda," Gallo admitted that he used Delavin to divert his attention when hie best friend, Edward Barber, and Heaven Peralejo were starting to have a romantic connection.

Gallo expressed regret for what he did, adding that he was clueless of Delavin's feelings for him.

In one "PBB"episode, Delavin broke down while confessing to Big Brother her love for Gallo, who said his heart already belongs to another housemate, Vivoree Esclito.

Gallo was evicted from "PBB" last Sunday.
