The British singer has been in a relationship with the producer - who won three Grammy awards on 12.02.12 - since the end of last year, after they worked together on his track `Summit`.

A source told The Sun newspaper: "Ellie and Skrillex are fans of each other`s music and met at the end of last year.

"They hung out in the studio as Ellie was featuring on his EP `Bangarang` and they got on really well.

"It has blossomed into something more than friendship, but it is still early days."

Ellie was dating Radio 1 DJ Greg James until late last year, when she was spending a lot of time in the US and was introduced to Skrillex - real name Sonny Moore - through industry contacts.

She has reportedly kept her new romance under wraps to avoid hurting Greg.

Another source told Us Weekly magazine: "It`s a really cool new romance and they get along perfectly.

"They`re really good together. Everybody thinks it`s awesome. Both of them are so talented. It`s a great Los Angeles romance for her now that she hasn`t been in London."

While Skrillex is one of the hottest new names in dance music, Ellie had a hit in the UK with her version of Elton John`s `Your Song`, and was personally invited to perform at the wedding of Prince William and Duchess Catherine.

Possibly alluding to Skrillex in a previous interview she has said: "It makes all the difference what producer you`re working with.

"The other day I just found somewhere where it was like, it clicked in my brain that I wanted to work with that person. And I won`t say who it is but I think it could be awesome if I end up doing stuff with him."
