"The first half of the year, the divorce happened and I just stopped eating," he said, adding that he continued to consume beer and he didn't start exercising. "I kept on drinking and all that stuff."
When Gifford asked him if he thought he stopped eating because he was grieving, he said that he just didn't think about it. "I feel like that happened so long ago that I lost some weight. Now it's like, 'How did I do that? I gotta do that again.'"

That's not all Shelton shared while on the morning show. The 39-year-old singer revealed that he will be hosting Nickelodeon's 29th Annual Kids' Choice Awards in March. We can't help but wonder if he'll be sliming his new girlfriend, Gwen Stefani.
"I wanna do this thing with kids. It's fun," Shelton said of his decision to host.

While Shelton made no mention of his new love interest on Today -- this was taped prior to the two making it official in Nashville -- he did make a joke about the type of woman he's interested in dating. When asked if he found women who play hard to get more interesting, Shelton quipped, "I don't have time for that crap. I want it now."
