Ed Sheeran has collaborated with Beats by Dr. Dre.

The 'Sing' hitmaker is seen in the official advert for Beats' new Solo2 headphones and the commercial also features a new track called 'Don't', which is lifted from his eagerly awaited second album, 'x'.

The video chronicles the 23-year-old singer's reaction to the events that inspired the new song, which is about a cheating ex-lover.

The song has long been rumoured to be about fellow pop star Ellie Goulding.

The lyrics include: ''I never saw him as a threat, till you disappeared with him to have sex, and I'm downstairs at my party and you're upstairs doing that, that's disrespectful.''

He adds: ''We make money the same way ... you were looking for a lover to BURN.''

Ed previously opened up about the track, admitting the lyrics are a lot tamer than what he could have written about his former girlfriend.

He said: ''I could have gotten nastier ... there was more s**t that I didn't put in.

''I was seeing someone for a bit of time, and then they ended up physically involved with one of my friends in the same hotel that we were staying in, while I was downstairs. And I feel like, 'Treat people how you want to be treated.' ''
