The 'Used to Love You' hitmaker, who recently sparked rumours she is dating her fellow 'The Voice' USA mentor following her split from Gavin Rossdale in August after 13 years of marriage, reportedly took a private jet with him to Nashville yesterday ahead of the 49th annual event, where he is nominated for a number of top prizes, including Male Vocalist, and is also set to perform.

A source claims the No Doubt frontwoman, 46, has no reason to be in the city except to be with Blake, 39, but they haven't decided whether she will attend the ceremony yet.

The insider told gossip website TMZ.com that while the pair are not in a serious relationship yet, they are enjoying spending time together, adding: "They could be in a relationship in the future but right now they're just good friends."

Gwen, who has three sons, Kingston, nine, Zuma, seven, and Apollo, 20 months, with her estranged husband, recently admitted she thinks the 'Sangria' hitmaker is "hot" but she's not ready to address the romance rumours "right now."

But she revealed they been comforting one another following the recent breakdown of their marriages, as Blake divorced ex-wife Miranda Lambert in July.

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."
