Bianca Gonzales should've thought twice before expressing her sentiments on cheating.

She is now under fire, simply commenting on a post justifying the same.

The post read in part, "...if your boyfriend cheats on you, you need to understand you lacked something that made him cheat..."

This didn't sit well with Bianca, who shared, "This mentality makes me sick..."

"To the boys who think like this, please be BETTER."

Though obviously she meant well, some fans deem her comment rather sanctimonious.

They were quick to remind Bianca of her days inside the "PBB" house, when she fell for then up-and-coming Zanjoe Marudo.

She was then in a relationship with Lino Cayetano.

After the reality show ended, Bianca and Lino decided to part ways.

Some of the comments:

"Naaalala mo pa ba nung kiniss mo si Z?"

"So pag lalaki hindi OK, kapag babae ok?"

"That post is indeed disgusting pero hindi si Bianca ang puwedeng magsalita diyan..."

"Dahan dahan sa pagpatol ng mga ganitong tweets kasi baka mag backfire..."

Thankfully, others went beyond prehistoric gossip and simply focused on the topic.

Said one, "Correct. Don't justify cheating. Don't blame yourself. Don't be a doormat!"

Added another, "Walang justification ang cheating. Ever."
