The Wetpaint Entertainment offices were alight with controversy yesterday when someone brought up the possibility that Voice judges Adam Levine and Christina Aguilera have hooked up.

It’s a fair question in light of their playful bickering on the past few weeks of Blind Auditions. The back-and-forth came to a semi-awkward halt this week after fellow judge Cee Lo Green told the two to “get a room!”

Both of the musicians blushed wickedly under the studio lights. Was it awkward because they don’t like one another, as the producers would have us believe, or because the Maroon 5 frontman and Xtina share a past?

The two have never been publicly linked in a romantic way, but Hollywood is a small place and they’ve definitely cavorted in the same circles for years. Is is possible they had a hook-up before Christina’s marriage to Jordan Bratman … or even after?
