It looks like things are heating up between NBC's "The Voice" co-hosts Blake Shelton and Gwen Stefani. Just over two weeks after it was reportedly confirmed that the two are a couple it seems they've made plans to spend the holidays together. 

According to Us Weekly, Shelton, 39, invited Stefani, 46, to his home in Oklahoma for Thanksgiving. Sources told the publication he also suggested she bring her three young children, which she shares with ex Gavin Rossdale, along. It remains unclear whether or not she accepted his invitation. 

Despite all the speculation and alleged confirmation of their romance, Stefani maintains that she is not dating Shelton. During an interview with the "Frankie and Geena Morning Show" on San Diego's channel 93.3 on Nov. 10 she was asked about her "new relationship" at which time she revealed to the show's hosts that she never confirmed she was dating anyone. In fact, she said she only heard the rumors after one of her eldest son's came to her about them.

Even with Stefani's denial, speculation continues. Just days prior to her radio show interview the "Used to Love You" singer visited Shelton in Oklahoma on Nov. 5, according to Us. She was joined by Maroon Five singer Adam Levine, who also stars on "The Voice." According to Entertainment Tonight, the "Sangria" singer wanted to give Stefani a "taste of the country life." Both Stefani and Levine, 36, shared photos from the visit, though something was noticably different about the two pictures -- Stefani cropped the "Sugar" singer out of her version.
