It's almost a month since the show finished, both Jade and Ed have not interest in engaging with her, she should just mind her own business and butt out. She is just making things up - Jade and Ed don't follow her on social media, and they would not share things with her. She wasn't responding to a fan of hers, it was a fan of Jade and Ed's asking why she feels the need interfere with their relationship. Judging by her response, she does feel she needs to interfere.
I'm sure she knows more second hand through other sources/HG's close to JadeEd than anyone on this forum does....
