So much for playing nice!

Season 18 of The View may have just wrapped its first week, but its co-hosts are already tangled in a web of drama, including reports that they're clashing off-screen.

Although the first episode went off without a hitch, come Tuesday, the always opinionated Rosie O'Donnell, and conservative newbie Nicolle Wallace, were already bickering on-camera, bringing back memories of Rosie's full-fledged fight with former host Elisabeth Hasselbeck in 2007.

The argument began when Nicolle defended columnist Charles Krauthammer, who recently made headlines for calling President Barack Obama a narcissist.

“Charles Krauthammer is a god in our world,” the Republican said. “[The] critique of President Obama…[is his] inability to have relationships…I think [Vice President] Joe Biden has an easier time with Congress because I think Joe Biden genuinely loves people.”

When Rosie, a well-known liberal, asked if she was implying that Obama doesn't love people, Nicolle confirmed she was.

“When Kanye West says, ‘I don’t think President Bush cares about black people,’ it’s like an international incident,” the comedienne retorted. “But you can say that you don’t think Obama likes people?”

While that moment was certainly uncomfortable, the colleagues' feud has reportedly continued behind the scenes.

According to a Page Six source, "Rosie and Nicole were still going at it after the cameras stopped rolling…Executive producer Bill Wolff had to call them both in and order them to calm down."

But a rep for ABC denies any tension. "This is absurd. It's just someone who is trying to stir up controversy," the network said in a statement.

Whether or not there's any truth behind the reports, we're confident producers will want to keep this gang around for a while. The premiere episode was the show's best opener since 2006, so it looks like Rosie's pre-season prediction was correct: "I think it's going to be must-see TV."
