Blake Shelton is a true Gemini in that he falls hard, and fast, and doesn't always think about tomorrow if he is happy with someone today. Case in point: his marriage to Miranda Lambert, a Scorpio. These two were both paired up when they met, but their attraction was so intense they had an affair.
Not too surprisingly, their chemistry wasn't enough to keep them together. Gemini and Scorpio, Air and Water, usually don't work out. Scorpios can be too intense for flighty Gemini. If Blake is as Gemini as he seems, he doesn't like to be alone, but also can feel smothered by a clingy partner... or even just the same one too long. They like to explore their options. And he might already be exploring a new love interest!
Now Blake is hooking up with Libra Gwen Stefani, his co-host on The Voice. These two Air Signs make a lot more sense. They can have a lot of fun together, and challenge each other to be their best, too. Interestingly enough, Gwen just divorced hunky rocker Gavin Rossdale... also a Scorpio. Coincidence?!
