Nikki Reed is reportedly dating Derek Hough.

The 'Twilight Saga' star - who announced her split from husband Paul McDonald in March after two years of marriage - is enjoying a ''fun'' fling with the 'Dancing With the Stars' professional dancer.

The 25-year-old brunette actress was spotted making out with Derek, 28, at Rock & Reilly's in Los Angeles on April 18, while they were enjoying a night out with friends, including Mark Ballas and Cheryl Burke.

An eyewitness told Us Weekly magazine: ''The whole group was drinking and partying. Derek bought shots for Nikki at the bar. There was lots of PDA, Nikki was feeding him, holding hands, and they left together. They didn't seem to care if anyone was watching.''

Nikki was also seen hanging out backstage at 'Dancing With the Stars' on Tuesday night (29.04.14).

An insider said: ''She's such a sweet girl! Really down to earth. They are having fun hanging out. It's a good match.''

But another source insisted their relationship isn't serious and they met through Derek's sister Julianne Hough, 25.

The source said: ''Nikki isn't currently dating anyone. She is focused on her divorce from Paul and caring for that relationship as well as her latest film projects. Nikki and Julianne are good friends, and she has hung out with Derek a few times through her. They're having fun but it's nothing serious.''

A spokesperson for Nikki previously revealed that she and Paul, 29, had been ''living separately'' for six months before their split ''due to work obligations,'' and added: ''They will continue to share their love of music, and are still working on their debut album, 'I'm Not Falling,' releasing in 2014. They remain best friends and look forward to their continued journey together.''
