Blake Shelton and Gwen Stefani hire wedding planner

Blake Shelton and Gwen Stefani have reportedly hired a wedding planner.

The couple – who started dating last year after the breakdown of their respective marriages – are believed to be planning to wed and have enlisted celebrity wedding designer, Jerri Woolworth to help them plan their big day.

TMZ reports that the couple are currently working on plans for their nuptials with Woolworth, who has offices in Tennessee and New York, but it is not clear if they have set a date.

Meanwhile, Gwen recently revealed she went through "months and months of torture" when her marriage ended.

The 46-year-old singer split from spouse Gavin Rossdale, 50 – the father of her sons Kingston, 10, Zuma, seven, and two-year-old Apollo – last year and though it has been speculated he was unfaithful with their children’s nanny, the ‘Make Me Like You’ singer insists very few people know what really happened.

She told the new issue of America’s Cosmopolitan magazine: "Nobody except for my parents, the people involved, and whoever they told [know specifics].

"Nobody would believe it if I could really say what happened. I went through months and months of torture."

Asked if she knew something was going on with the Bush frontman, she added: "All you have to do is listen to every single song I’ve ever written and it’s all there. It’s an ongoing theme that I’ve had for a long time."

These days, Gwen is much happier as she’s found love again with her fellow ‘Voice’ coach Blake, 40 – who split from wife Miranda Lambert, 32, around the same time – but she admits she was initially reluctant to get involved because they both had "trust issues".

She said: "We were both having trust issues, as you would if you were us.

"It was like, ‘I have so many problems. How can I now be getting into another potentially huge problem? What am I doing?’"
