Levi Johnston opens up to ET's Mark Steines about rocky relationship rumors about former Vice Presidential candidate Sarah Palin and her husband Todd.

In the interview, Mark asks Levi, "Do you think this relationship is headed for divorce?"

Levi responds, "I'm sure it is. Just like she decided she was going to quit [being the] governor [of Alaska], just was waiting for the right time, they're gonna wait it out. They're gonna be smart, they're do it when the time is right."

He said he overheard arguments at the Palin household where divorce was mentioned, and he also claims his ex-girlfriend Bristol, who is the mother of his infant son, Tripp, suspected that her father possibly had "something going on" when it came to affair rumors. He did say that he saw no indication himself of any possible affair.

Levi says of Sarah and Todd, "I've never seen them like a normal married couple. You know, the communication was horrible, they never talked, really wouldn't be in the same room. You know, they'd fight a lot."
