Is it time to break out the vuvuzela on American Idol?

The House That Had Its Mortgage Paid Off by Carrie Underwood will rock an “Arena Anthems” theme for Top 6 week (next Wednesday, April 22, 8/7c on Fox), TVLine has learned exclusively.

According to an Idol insider, that means the heirs to Caleb Johnson’s throne will be performing “songs that can entertain a massive crowd and are performed by mega superstars.”

What’s more, TVLine has learned that U.S. Women’s National Soccer Team stars Abby Wambach and Alex Morgan are scheduled to appear on the episode to help make “a very special announcement.” (Could it be a game-changer for the remaining contestants?)

Wambach holds the world record for international goals – men or women – with 178 in her career, while Morgan has scored 51 times in her first 84 games for the USA. Both are expected to play key roles for Team USA in this summer’s FIFA Women’s World Cup 2015, which will be broadcast on Fox and its related networks.
