ET was at the iHeartRadio Music Festival in Las Vegas over the weekend where we caught up with all the major stars including Ariana Grande, who slammed recent headlines calling her a 'diva.'
"If any of the things that they were saying were true, I wouldn't mind it," Ariana told ET special correspondent Elvis Duran. "Since they're not, I just sort of have to focus and stay on track and do what my family has always told me, which is just: 'Know my truth, work hard, be nice to everyone you meet, not fight back and just be a lady.'"
While Ariana has been making headlines in a less than favorable light, Iggy Azalea has been the talk of the town for all the right reasons. She's featured in Jennifer Lopez's Booty music video, which has had everyone buzzing.
"I almost had a seizure watching the Jennifer Lopez video -- so much booty," said Iggy.
Following the booty trend, Meghan Trainor's All About That Bass has become the No. 1 song in the country.
"I didn't even plan this," said Meghan. "I'm just proud I'm a part of the butt movement and the body-positive stuff, and it's amazing."
Watch the video to hear Taylor Swift talk about her secret to always looking flawless.
