The 2017 iHeartRadio Music Festival didn’t disappoint. While P!nk, Miley Cyrus, Coldplay and more artists' performances sent the hashtag #iHeartFestival trending worldwide, there were tons of moments that weren’t caught on the stream. Check out the best behind-the-scenes tidbits below:

WAKEY WAKEY:

To kick off the weekend, Ryan Seacrest woke up performer Noah Cyrus live on air by calling her hotel room early Friday morning.

“This is a beautiful wake up call,” Noah said, admitting that she was still in her hotel bed with the blackout curtains drawn. “It’s still pitch black. I’m very excited to be here.”

TANYA JOINS LITTLE MIX:

The group presented during Friday night’s show before performing at the Daytime Village Presented by Capital One at the iHeartRadio Music Festival on Saturday and while making their way backstage through the hall, Tanya opted for a photo sesh.

BACHELOR NATION:

 Bachelor hunks Peter Kraus, Ben Higgins, Dean Unglert and Wells Adams reunited along with Becca Tilley and Ashley I. The group all went to dinner Thursday night before hanging backstage and in the crowd at the festival.

BEBE REXHA HITS ON BACHELOR'S PETER:

Even songstresses like Bebe Rexha caught sight of the Bachelor hunks. While making her way to the stage, the singer ran into Peter in the presenter green room and asked for a photo. “Wow! You are one of the hottest guys I’ve ever seen in my life,” she was overheard exclaiming. “Can you come take a pic?”

BEBE SAID SHE WORE 3 PAIRS OF SPANX:

The actor was overheard saying how good Ryan’s complexion was and that he wanted to get ahold of Ryan’s skincare line, Polished, while backstage at the Daytime Village Presented by Capital One at the iHeartRadio Music Festival on Saturday. He was also heard praising Bebe's amazing voice.

KHALID IS THE NICEST GUY EVER:

The “Young Dumb & Broke” singer was the sweetest while greeting fans at a meet and greet held at the Village on Saturday.

KESHA LIKES HER SPACE:

Later that night at the festival, Kesha held a meet and greet but there were a few rules: No hugging and pics were in groups of four.

PUPPIES!

Did we mention there were puppies around? And that Noah Cyrus adopted one after taking snaps with one at the Village?! Because that happened too. She was later overheard telling Elvis Duran that she adopted the puppy to help her get over her most recent breakup.

MILEY ASKED LIAM'S PERMISSION TO ADOPT A DOG:

After telling Elvis Duran that she couldn’t adopt another dog or she’d get dumped, Miley was overheard asking someone to take a photo of her with one of the rescue pups and to “ask Liam if we can please get him!”

KYLIE COVERS REPORTED BABY BUMP:

The reality star made her first public appearance since news broke that she’s allegedly pregnant with Travis Scott’s baby. The Lip Kit creator was spotted backstage in an oversized shirt while cheering on her man who performed with DJ Khaled
