Selena Gomez's friends are reportedly ''a little bit wary'' of her new romance with Zedd.

The 22-year-old singer, who split from Justin Bieber last October after almost five years of dating, is ''having fun'' with the DJ, but her friends are worried she could get her heart broken again.

An insider said: ''Selena's friends are a little bit wary while remaining hopeful, but ultimately right now he is making Selena happy and he is not Justin Bieber so that's a good thing.''

The 'Rudderless' actress is ''really happy'' to be dating the Russian-German music producer, 25.

The source told E! News: ''Everything is going great with him. She is really happy and they are having fun.''

The pair, who are collaborating in the recording studio together, first sparked dating rumours when they were spotted holding hands at a Golden Globe Awards after-party earlier this month.

Zedd - real name Anton Zaslavski - flew to Atlanta, Georgia last weekend to spend time with the actress while she shoots her upcoming film, 'The Fundamentals of Caregiving,' alongside Paul Rudd and Craig Roberts.

The 'The Heart Wants What It Wants' hitmaker was also spotted signing autographs for fans who showed up to the set during a break.

An eyewitness said: ''At one point, Selena walked off set and interacted with her fans. There are about 16 young girls there, Selena was nice to each person. She took photos and said hi to them. She was really sweet.''
