Gwyneth Paltrow: 'Glee' And Kings Of Leon Mediator

Gwyneth Paltrow: actress, Goop chief, mother, singer... and peace mediator?

Paltrow, who is set to appear in her second set of guest appearances on "Glee" this season, helped the show's creator Ryan Murphy bury the hatchet with the rock band Kings of Leon, according to The Hollywood Reporter. And based on their rivalry, it was no easy task.

In December, Murphy sounded off about the Kings of Leon and their refusal to grant 'Glee' the right to cover their songs on television. He was, to say the least, less than pleased, saying:

"F--- you, Kings of Leon. They're self-centered assholes, and they missed the big picture. They missed that a 7-year-old kid can see someone close to their age singing a Kings of Leon song, which will maybe make them want to join a glee club or pick up a musical instrument."

Nathan Followill, the band's drummer, fired back on Twitter, saying, "Dear Ryan Murphy, let it go. See a therapist, get a manicure, buy a new bra. Zip your lip and focus on educating 7yr olds how to say f**k."

Many saw the rant as homophobic, though Followill later denied that intent.

In stepped Paltrow with a little text message diplomacy. All of a sudden "it's all good now," as THR reports, and "Glee" stars Darren Criss and Chord Overstreet even went to the Kings of Leon's Grammy after-party.

You can catch Paltrow's "Glee" episodes in March -- she plays a Spanish teacher that has a fling with Matthew Morrison's character.
