"It was at someone's house and there was quite a few people there, but we sat across from each other," Lovato said. "It was just fun to catch up and see each other."

As for scheduling another hangout, the 23-year-old pop star says they've been "too busy."

After all, both ladies have albums coming out next month. Lovato's Confidence will be released on Oct. 16, one week after Gomez's Revival comes out on Oct. 9.

While Lovato supports her longtime friend, she does admit that she's yet to listen to Revival. "I really want to hear her new music," she said. "I like new stuff."

Lovato does seem busy but she will have to set aside time for Iggy Azalea and Nick Young's wedding. She confirmed again that she'll be acting as a bridesmaid on the couple's big day, but doesn't have much info on the nuptials.

"I think she's taking her time but yeah I’m excited," Lovato shared. "We’ve become pretty close over the past year."
