Is there a rift between Adam Levine and Javier Colon, the winner of Season 1 of ‘The Voice‘ under Levine’s tutelage? It sure sounds like it, even though the men seemed so close after working together during the series’ debut season in 2011. Apparently, Levine is refusing to take the stage with Colon and egos appear to be at play.

For tonight’s elimination episode (May 1), last season’s Final Four are returning to perform. Three of them will sing with someone famous – Dia Frampton with Kid Cudi, Beverly McClellan with Cyndi Lauper and Vicci Martinez with Cee Lo — but Colon will go solo. WTF?

Perez Hilton reports that Colon is singing a la carte because he wanted to partner up with Levine, who refused. An even bigger WTF, right?

A source claims, “Adam said he would only consider collaborating with Javier for the performance if it was a cover. Not his original song. Javier wouldn’t budge and neither would Adam.”

Guys, what’s up with that? A few months ago, for his OUT cover story, Levine likened Colon to family. We are beyond bummed to hear this. We’ll cling to some hope that the two will pull out a surprise performance tonight. One can wish, hope and dream, right?
