Domestic bliss? Not quite.

Married for a month-and-a-half, Kim Kardashian and Kris Humphries have learned the hard way that cohabitation involves a whole lot of give-and-take.

As a new clip from part one of the couple's E! special shows, Kardashian, 30, is having trouble warming up to her husband's bathroom hygiene habits.

Getting ready for bed in their shared bathroom, Kardashian fumes when Humphries, 26, doesn't brush his teeth to her liking.

"Can I tell you what another of my pet peeves is? Someone that brushes their teeth so hard that they make the entire mirror all [soapy]," she tells him.

Humphries brushes his wife's tirade off, but things get even more tense when they head to bed and the basketball star invites his dogs to sleep in their bed.

"They're not allowed in my bed -- that's silk right there," she snipes.

The newlyweds' wedding extravaganza will air in a two-part special -- Kim's Fairytale Wedding: A Kardashian Event -- on E! Sunday, Oct. 9 at 8 p.m. and Monday, Oct. 10. at 9 p.m.
