Personally I'd rather if I liked them see the real artiste.
If that's not the case just listen to their music or watch their videos of recordings or concerts.

However, there's lots of tribute acts for Stars.
I don't see the point of them being sued.

I'd see it as a tribute myself.
Anything that keeps you in the spotlight and draws attention to your songs can only be a good thing.
As long as it's done in respect.
