Maybe not, but they do reveal a bit of info. Plus, Mashima gives little hints in it. ;)

Like the one interview (forgot the volume) where Mira & Lucy were talking about the boys peeking at the girls bathing before the GMG arc, & Mira categorizes the guys by saying that Natsu wanted to peek on Lucy, Gray on Juvia, Jet on Levy, & Droy on everyone. XD
