Christina Aguilera collaborating with boyfriend on next album

London -  Christina Aguilera has reportedly given her boyfriend a huge break in the music industry by enlisting him as a songwriter for her next album.

The crooner fell for production assistant Matthew Rutler, when they met in 2010 on the set of her movie musical ‘Burlesque’.

Now, the 31-year-old actress is taking their relationship to the next level - and making sweet music together for her upcoming seventh studio release.

"Matt has come a long way from being a production assistant on Christina's movie Burlesque. He's now a songwriter, working on new tracks for her new album. People will be surprised by the sound they've put together,” the Daily Express quoted a source as telling JustJared.com.
