Music superstars Jennifer Lopez and Iggy Azalea are reportedly set to perform their infectious “Booty” remix at the upcoming American Music Awards but have television network executives concerned.

According to reports, ABC executives are worried about how explicit Sunday’s set will be.

Our spies tell us … Iggy and J.Lo will perform “Booty” … and network honchos are nervous … real nervous. The execs have set the ground rules … no cracks, no rubbing. There will be a 3-4 second delay, but these shows have a rich history of raunchy performances slipping through … the cracks. It’s interesting … we’re told ABC has not put the kibosh on spanking … something fairly prominent in the music video. But that’s as sexual as execs will allow. (TMZ)

Check out what Iggy said about the upcoming performance right here…

Iggy has already jumped onto her Twitter page to promote the awards show.

Last month, music mogul Diddy also compared J. Lo’s booty to reality television star Kim Kardashian‘s.

But when Billy asked if Kim’s butt is even in the same conversation—the rapper gave a pretty powerful answer. “No way,” Diddy said. “No way, no diss to Kanye [West] and Kim but that thing right there, that thing right there is something special.” (In Touch Weekly)

A couple months ago, Lopez touched on the attention Iggy had received over her lower backside.

When asked if she feels like she’s passing on the booty torch to the Aussie rapper, she laughed and told us, “We’re in it together! It’s not about passing torches or anything.” Lopez continued, “There’s room for every artist, all types of artists, all the time. I’m not one of those people that needs to be the queen or anything like that, I just feel like I want to share my music and perform and share love with people.” (E! Online)
