Christina Aguilera wants her ex-husband to help her revive her music career.

The 'Your Body' hitmaker - who gave birth to daughter Summer Rain, her first child with fiancé Matthew Rutler, last month - has reportedly reached out to music executive Jordan Bratman, with whom she has son Max, six, for advice for her next album.

A source said: ''Jordan is the only one she can trust to get a hit song on the radio. She's been calling him non-stop and even offered to pay for advice.''

But the insider said her 37-year-old ex-husband isn't interested in having a professional relationship with the 33-year-old blonde beauty.

The source added to America's Star magazine: ''Jordan has declined her attempts to set up business meetings.

''Co-parenting is as far as he will go.''

Christina and Jordan split in 2010 after five years of marriage shortly after she returned from filming the movie, 'Burlesque,' on which Matthew was a production assistant.

After confirming their split, she explained: ''When I finished filming, I didn't feel right in my own shoes [at home]. I had a lot of things stirring inside of me that I felt were being suppressed. We tried to work on the marriage and figure out a common ground. But the problems were obvious.''
