What would you do if you caught your friend's partner cheating? That’s one situation no one wants to be caught in. 

But for Sheila Sim, she seems to know exactly what she would do.

In a recent interview with vibes by 8world, the 42-year-old actress and her Keep It Down co-star Romeo Tan were asked the question.

"Actually, between friends, in private, we often discuss this topic too, like [what should I do] if my friend's husband was cheating on her," said Sheila.

"I think those who are married, many would think it's better not to tell them," she added.

To Sheila, a better way to approach the situation would be to talk to her friend's partner, aka the cheating party, instead of directly dropping the bomb on her friend.

"Because if anything happens between them, you'd be responsible for it, especially if they have kids," she explained.

Romeo, however, shared that if it were a very close friend, he might choose to inform them "in order to protect them".

So, would Romeo tell Sheila, who cleverly turned the question on him, if he caught her husband, Deon Woo, cheating?

Sheila and the local bank executive got married in 2018 and now have two daughters, Layla, six, and Skyla, three.

"That is something that would not happen. I trust that Deon is not that kind of person," declared Romeo.

But when Sheila responded, "I believe he won't too, but if he did, would you tell me?", the actor did decide to skirt the question. We hope Sheila never has to find out Romeo's answer then!
