The 'Little Red Wagon' singer split from her husband in July and he has reportedly moved on with his fellow 'Voice' coach, and his estranged wife wasn't surprised to hear the news as the pair have always been "flirty".

A source said: "She was not surprised to hear of the romance between Blake and Gwen. They were always pretty flirty.

"Miranda and Blake were on the rocks on and off and knew that this could always be a possibility.

"Blake is just a flirty kind of charmer.

"She has nothing against Gwen and thinks she is a very talented artist. Whomever Blake is with she wishes them the best."

Meanwhile, the 31-year-old beauty isn't looking for love herself as she is focusing on her career.

The source told E! News: "Miranda is at a point in her life where she is really focusing on herself and her music. This is a new chapter for her to create new relationships and really move on.

"Miranda has been going through many personal changes over the past few months, but it's all for the better."

Gwen - who split from husband Gavin Rossdale, the father of her three sons, in August - recently admitted she thinks 39-year-old Blake is "hot".

She said: "[I] think he's hot, don't you?"

Despite insisting she's not ready to address the romance rumours "right now," the 46-year-old singer admitted the talented duo have been comforting one another following their divorce from their former partners earlier this year.

She explained: "To be super honest, it is kind of crazy we both went through the same thing at the same time.

"There's been so many people that I've got so much comfort from. Just people coming to me and telling me their story, not confiding, but sharing, which has just helped me see things from a different perspective and move forward."
