FOXSteve Van Zandt’s wife Maureen is standing up for her man, after the E Street Band guitarist, songwriter and producer was seemingly dissed by Jennifer Lopez on Thursday night’s edition of American Idol.

Van Zandt was tapped by American Idol’s in-house mentor, Big Machine Records label head Scott Borchetta, to mentor the remaining contestants for “Classic Rock Songs Week” on the show. MacKenzie Bourg, one of the final four contestants, performed a rendition of Cheap Trick’s “I Want You to Want Me,” for which he and Van Zandt tried several different arrangements before deciding on the final one.

J-Lo said, “You MacKenzie’d it. I don’t know that I loved how you MacKenzie’d it…I would’ve loved to hear what you did originally, y’know, before…uh…” She then blanked on Van Zandt’s name, asking fellow judges Harry Connick Jr. and Keith Urban, “Mentor?” Keith joked, “Cheap Trick,” but Harry said, “Steven.” “Yeah,” J-Lo laughed, before going on to speak more about the performance.

Well, Maureen Van Zandt didn’t like that one bit. In a series of tweets, which have apparently since been deleted but were seen by Billboard, she wrote, “Really @JLo needs to f**k off,” adding that her comments “shows how little homework she does. Or how little she retains. And Stevie did not do that arrangement.” She ended by saying, “She knows nothing about the rock world. And is a music judge?”

One comment still posted reads, “I see it this way. She gets $20 mil to do a job. If she doesn’t know the name of the mentor that is not doing her job.”

So far, JLo hasn’t commented.
