The Kapuso actress said she is "no longer together" with the actor and said she would rather keep details about their split private.
"I'd rather keep the details private as I want to give the break up the same amount of respect that I had for the relationship," Andrea said.
"I think you all know how much it meant to me. I hope you understand. I will always wish him and his family well," she added.
It was Derek who first confirmed the break-up after replying to a netizen, defending Andrea from online speculations and saying that there was no party involved.
Rumors of the break-up began when both removed their photos together on Instagram. In addition, Andrea unfollowed Derek on the social media platform.
