Gwen Stefani ‘Head Over Heels’ About Boyfriend Blake Shelton, Source Says

This isn’t puppy love. Even though Blake Shelton and Gwen Stefani have been dating for only five months, the pair is already said to be pretty serious about each other.

Sources close to the couple told Us Weekly that Stefani is “head over heels” about the country singer and has fully moved on from her split with ex-husband Gavin Rossdale. The No Doubt singer and Rossdale divorced in August, while Shelton and his ex-wife, Miranda Lambert, ended their four-year marriage in July.

“She’s in a good place,” the source said, adding that her romance with Shelton is “definitely serious.”

In fact, things are going so well for “The Voice” judge and Stefani that he bought her a horse. The “Used To Love You” singer, who named the animal Halo, introduced him to fans via an Instagram post in January, calling it the “best present ever.”

“We got her horse, and I got myself a horse at the same time,” Shelton told “Entertainment Tonight” earlier this week. “Gwen, she loves riding, and she loves horses. It’s actually so funny that people are so shocked by that, but if you can name me one girl on the planet that doesn’t love horses or just think that they are beautiful…”

Stefani recently opened up about her and Shelton’s romance, telling Jimmy Kimmel on his late night talk show that her new song “Make Me Like You” is about her new beau.

“I will admit that song is about that guy,” she said (via USA Today). “What’s so crazy is that sometimes tragedy — if you really absorb it, you can turn it into something beautiful. This whole album is about trying to take something awful and, just, I don’t know, healing from it and then turn it into something beautiful.”
