That's certainly April, and the girl next to her almost looks like Diana C8 but the girl with the red cross definately is not Jade, that is not her profile.
That could be a mistake on the part of the sender. What's even more baffling is how people can question Marjorie's wedding pictures when her name and agency are clearly credited on the website.
I guess you're right about "Jade" though. That doesn't look like her nose. But the person who emailed it to me said it was... so... T_T;;
