'Bachelor in Paradise' Sneak Peek: Josh Confronts Evan for Talking to Amanda

— -- There's a new rivalry building on "Bachelor in Paradise."

In a preview for tonight's episode, Amanda Stanton is seen telling her cast-mates that Evan Bass warned her against dating Josh Murray.

That obviously didn't sit well with Murray, who was previously engaged to former "Bachelorette" Andi Dorfman.

"You know that you don't just go behind people's backs and talk about them," he told the camera. "To hurt a relationship just for you to possibly stay here, that's just a very immature thing to do."

Toward the end of the clip, Murray asked Bass to speak with him as the others watched.

In last week's episode, Bass tried to flirt with Stanton, who had already begun dating Murray.

"True love is something that's worth taking risks for," Bass explained.
