Nick Cannon Swears Mariah Carey Really Doesn't Know Who Kim Kardashian Is

Kim Kardashian might be one of the most famous women in the world, but Nick Cannon stands by his claim that wife Mariah Carey really doesn't know who she is - or the reality star's famous booty.

'If there was a lineup of brunette girls with big butts and Kim was in that lineup, I guarantee you my wife would not be able to pick her out,' the America's Got Talent host, who dated Kim in 2006, told Life & Style.

'She just doesn't pay attention to stuff like that. She doesn't watch reality television. She's focused on her album and her music. She kind of does her own thing. I don't blame her because she doesn't get caught up in the gossip and all that.'

Ouch - another burn for Kim just weeks after Nick inferred she's slept with a lot of people since they broke up.

Late last week, the 33-year-old was on Howard Stern 's radio show when he made the initial 'Mariah doesn't know who Kim is' statement and admitted he got in trouble with his leading lady after he publicly discussed his sexual conquests.

'The thing is when she heard that, she heard it secondhand. Someone told her. It wasn't like she was tuning in,' he said.

'She was like, 'just shut your mouth sometimes please.' But she doesn't pay attention to that stuff.'

So what does she pay attention to? Their soon-to-be 3-year-old twins, Moroccan and Monroe a.k.a. dem babies.

'She hangs out with the kids,' he shared. 'Ask her any Pixar/Disney character; she knows all of them because of my kids.'

He also made sure to praise the legendary songstress.

When asked what his favorite thing about her is, he said, 'Her heart! More than anything. She's the most nurturing, amazing person.'

And - let's not forget - after boasting about his 'list' of hookups, which included names such as Kim, Christina Milian, and Nicole Scherzinger, Nick wanted to make sure he discussed his private time with Mariah.

He told Howard, 'The most amazing sex I've ever had is with my wife.'

That's how you save the day, fellas!
