Nick Jonas has made a conscious choice to stay single, insisting he wants to focus on his career.

The Jealous singer ended his relationship with Olivia Culpo last year (15) and has since been linked to actresses Kate Hudson and Lily Collins and singer Selena Gomez. Despite all the rumors surrounding his love life, the 24-year-old insists he is single.

"It's been challenging to find any time on that front," he tells LA Confidential magazine. "But it's also a choice I made to just have this season of my life be solo, so that I can make the most of all I'm trying to accomplish. I've got plenty of time, at 24. I mean I hope I have plenty of time!"

Nick recently released his latest album, Last Year Was Complicated, and he has previously spoken about using his breakup with Olivia as an inspiration for the record. The singer knew his fans would be able to relate to the overall theme of losing someone close to them.

"Heartbreak is a theme that a lot of people relate to...," he says. "I saw pretty quickly that it was a lot of what my fans could relate to. It's nerve-wracking when (the feelings) are as personal as the ones that I shared were. But I feel relieved when I use my writing as a way to process - it's very therapeutic."

However, even though Nick poured his heart out in his music, he isn't ready to discuss the specifics behind the split.

"I was with (Olivia) for two years," he told radio host Ryan Seacrest earlier this year (16). "We had a beautiful relationship together and it was great. It was time for that to end, which is sad."
