Sure they're extensions, but when they look this good, who cares?!

Gwen Stefani and her middle son Zuma ran errands in Brentwood on Monday afternoon, and the singer showed off her long blonde mane and rocked a whole lotta denim. Gwen wasn't her usual smiley self, but she still looked incredible.

So what's going on with new beau Blake Shelton? The two have been inseparable since they started dating, and they recently attended a wedding for Shelton's stylist in Nashville, but don't buy into those rumors that Gwen is pregnant. In an interview with Entertainment Tonight on Sunday, Blake said, “I think it’s awfully early to be talking about that, don’t you?” Shelton said. He added that while the two are happy and doing well, they won't be moving in together anytime soon either. And there you have it!
