Hmm, depends! Tina has been, admittedly, out of the game for quite a long time prior to this stuff. I'm kind of playing it as "she had fame, and then lost a lot of it". But feel free to have heard about Tina, EVERYONE. She'd probably know about Rae but that's probably about all-can't have the squeaky clean teen pop-idol image ruined by associating with a sex bot, after all.
