UPDATE: Holmes’ rep says the rumor is not true. (Thank goodness.)

Even if Julia Roberts doesn’t make a guest appearance on Glee, there’s a very good chance another Oscar winner will.

According to Entertainment Weekly, one of Julia’s co-stars is reportedly scheduled to visit the FOX series next season. Javier Bardem, who also worked with creator Ryan Murphy when he directed Eat Pray Love, reportedly pitched the idea of a cameo.

So what will the No Country for Old Men star do on the comedy? “We’re going to rock the house,” Javier said about playing a rock star who becomes friends with the New Directions’ Artie (Kevin McHale). “We’re going to do some heavy metal — Spanish heavy metal, which is the worst.” (In the event you’re wondering about Bardem’s singing abilities, he was original supposedly to star in the film adaptation of Nine.)

Meanwhile, it’s being rumored that Katie Holmes has snagged a five-episode arc on the series as well. Holmes reportedly developed a relationship with Murphy after working with Dianna Agron on the upcoming film The Romantics.
