no, they're suing because they thought they signed a contract for characters of them to be featured during their own songs as a group, and not during anyone elses songs or any other part of the game. Here's a better
link than that tmz crap, with actual official statements. they have every right to be mad over it. it's not like anyone in that band needs more money, it's the prinicpal of it. and this band does and gives so much money to various charities it's ridiculous. The only other lawsuit I know Gwen has been involved in is when her clothing company sued Forever 21, which she had every right to, that store is terrible. I know you're trying to be funny with the whole "her mother" thing, but I mean c'mon. I'm sure if an image of you was used in a way you didn't want it to be, you'd be angry and if you could sue over it, you would.
