Ohhh his parents! I’m sure they’ll have an idea. What’s the Instagram account they follow that comment on Rebecca?On left picture, it's Rebecca and yes, she does look totally different (again). On the right pic it's his ex from last year at the same event.
I think OP was wondering about HIS parents. I mean, his parents follow that one "gossip account" on IG where people often comment about Rebecca, I think they must have noticed some comments. However, if they did their own research, who knows.
