Is Kourtney Kardashian's man really the "Boyfriend From Hell"? During a Thursday call for radio show On Air with Ryan Seacrest, Scott Disick fired back at a new tabloid cover story alleging trouble between him and Kardashian, 30 -- not to mention the rest of her famous family.

The most heated issue? His fiery relationship with Kourtney's mom, Kris Jenner, who has frequently lashed out at him on Keeping Up with the Kardashians. "When I hear Kris' voice, I hear anger at all times," Disick, 26, told Ryan Seacrest.

But he's hopeful that things can be mended: "Honestly, deep down, I think we both love each other a little bit, and I think that will come to the surface in due time. We already are getting along better these days," he said.

He charges that Jenner has caused tension with the jocks in Khloe and Kim Kardashian's lives, Lamar Odom and Reggie Bush."I care for both of the athletes that are in the family," he said. "Kris just thinks that if you're an athlete you tend to be a better person, when that's not always the case." (Kris' husband is former Olympian Bruce Jenner.)

One topic that's not hard to discuss: baby son Mason Dash, born in December. "It's unbelievable. It's definitely more than I ever could have imagined it would be," he exclaims. "It gets better per day. Everyday is a new adventure with him."
