Gavin Rossdale and Gwen Stefani
The 42-year-old singer and husband Gavin Rossdale have been a couple since 1995. They have been married since 2002 and have got two songs togeher.
Their relationship was rocked when a paternity test revealed Gavin had previously fathered Daisy Lowe with ex-girlfriend Pearl. Courtney Love also claimed that she'd had an affair with him.
Gwen is said to be doubting her long-time partner, Music-News reports.
"Things have gone from bad to worse and they don't know how to fix it. They've been through a lot and while Gwen's putting on a brave face for the sake of the kids, she's not sure she can save their marriage," a source told British magazine Closer.
Gwen has reportedly suggested a temporary break from each other.
"Gwen isn't sure she can trust Gavin any more. They need time to figure things out, but he's now on a six-month world tour with Bush until the end of June - although he tries to come back when he can to see the kids," the insider added.
"Rather than trying to have a long-distance relationship, Gwen suggested a trial separation to see if a break would prompt him to show her how much she means to him."
