Gwen Stefani thinks Blake Shelton is "hot." The 'Voice USA' mentor, who celebrated Halloween with the hunk in Los Angeles last weekend, is remaining coy on whether she's dating her newly-single co-star, but has admitted she does find him very attractive. Speaking on radio with Ryan Seacrest, she said with a cheeky giggle: "[I] think he's hot, don't you?" Despite insisting she's not ready to address the romance rumours "right now," the blonde beauty has revealed 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.”
