The on/off friends recently posed for a picture together at a mutual friend's house party and the 'Cool for the Summer' hitmaker has revealed she and Selena spent some quality time together at the bash.
She told 'Entertainment Tonight': ''It was at someone's house and there was quite a few people there, but we sat across from each other. It was just fun to catch up and see each other.''
Demi and Selena, both 23, sparked speculation they had a falling out in 2014 when Demi unfollowed Selena across her social media platforms.
When asked why she had dropped Selena, Demi said on 'Watch What Happens Live': ''I think it's just one of those things where people change and people grow apart.''
But it seems the former Disney child stars have patched things up, with Demi recently re-following Selena on Twitter.
As for another catch up, the former 'X Factor' USA judge admits both she and Selena are ''too busy''.
Both singers have new albums due for release in October and Demi can't wait to hear what the 'Good For You' hitmaker has cooked up.
She added: ''I really want to hear her new music. I like new stuff.''
His new album Underneath It All is out now.
