Josh Duhamel reportedly wants Fergie to distance herself from

The 'Safe Haven' star is trying to encourage his wife to return to her solo career, but feels the only way she'll gain success is if she lets go of her Black Eyed Peas bandmate.

A source told ''Josh is pushing hard for Fergie to make a much cleaner and clearer break from The Black Eyed Peas so she can re-invent herself as a solo artist without the looming spectre of influencing every creative decision she makes.''

Fergie - who has four-month-old son Axl with Josh - is reportedly struggling with her self-esteem, but the hunky actor is adamant he'll boost her confidence.

The source explained: ''Josh is her biggest fan and he's getting a lot more assertive and interested in Fergie's business. He wants to drive a more permanent wedge between her and will.''

The 38-year-old singer - who hasn't released a solo album since 2006 - recently said would be handling the production of her second solo release, but it is now believed she is beginning to side with Josh.

The source added: ''She says she doesn't need will and the only way to shine is to eliminate him from the picture.

''Josh would love her to get back on top as a solo artist - he really believes she has more talent in her little finger than all the female pop stars in the charts right now put together.''

The Black Eyed Peas - also consisting of taboo and - went on a second hiatus last year, but insisted the band would be working on their seventh studio album this year.
