VIDEO : How Did Gwen Stefani Make Blake Shelton Jealous On 'The Voice'?

On Tuesday night's 'The Voice', things got flirtatious between Gwen Stefani and contestants Chris Blue and R.J. Collins of Team Alicia. The pair performed a cover of Miguel's "Adorn" and when it was time for the coaches to give their feedback Gwen wasn't focusing on their vocals. Gwen told Chris, "I don't even know if I was listening to your voice because I was so mesmerized by your body." Her compliments didn't stop with Chris either. To R.J. Gwen said, "R.J., I didn't know you were 18 years old. I mean, you look like a man, ya know?" Gwen went on to exclaim that she wanted to see them perform again and her boyfriend and fellow coach, Blake Shelton yelled, "That is enough!"
