rockstar performed Wedding of Demi Moore and Bruce?

That's an interesting question! While the wedding of Demi Moore and Bruce Willis was a star-studded event, there's no record of a band called "Rockstar" performing at the ceremony.

Here's what we know:

* The wedding was a very private affair, held in a small chapel in the woods of Idaho.

* The ceremony was officiated by a friend, not a traditional officiant.

* The couple's close friends and family were in attendance, making it a more intimate celebration.

It's possible a band was hired for the reception, but the details of the entertainment have never been publicly released.

So, while we don't know for sure, it's likely that a band called "Rockstar" wasn't involved in the wedding ceremony.
