Nick Jonas doesn't talk to exes

Nick Jonas no longer speaks to his exes Miley Cyrus or Olivia Culpo.

The 23-year-old singer had his first kiss with Miley almost 10 years ago and went on to date her for 18 months and Nick split from Miss Universe Olivia in 2015 after two years of dating but says he doesn't keep in touch with either of them.

Speaking about Olivia, he told Entertainment Weekly: "I haven't heard from her in a year. I don't know if I'll hear from her again. I'm not sure."

And when asked about Miley, 23, who recently rekindled her romance with Liam Hemsworth, Nick said: "I don't have a relationship with her now really, but that's not because we have any bad blood--we just sort of run in different circles. I love 'Wrecking Ball' so much. I still think it's one of the best pop songs of the last 10 years. And you know, she's always been outspoken and authentic to who she is, so it was only a matter of time before she really owned that, and I'm proud of her. ... It's a lot like watching your high school crush do well, just on a bigger scale."

Nick also revealed that Olivia inspired a number of tracks on his latest album 'Last Year Was Complicated', and he often wonders if she has heard it and what she thinks.

He said: "I've thought a lot about whether she's heard it, and I'm sure she's heard 'Champagne Problems' at this point. The concept of the song, which maybe doesn't stand out on first listen, is, 'You're amazing, you're all the things I hope to find with somebody, but timing, circumstances, all these things play into it not being right.' Champagne is amazing; it tastes delicious but gives you a really bad hangover. That's the idea..."

Nick was linked to Kate Hudson following his split from Olivia but recently admitted he has enjoyed a few dates with Lily Collins.

He told The Sun: "We went out a couple of times. She is amazing.

"We have known each other for years, just running in the same circles.

"I've enjoyed meeting different people and spending time with people with all the cards on the table. All people need human interaction at some level. And at my age too, dating is important, getting to know yourself by meeting different people, seeing what it's all about."
