Kim Kardashian Adjusts Her Business Plans

Kim Kardashian headed to several meetings in Beverly Hills on Thursday, where she adjusted her high-waisted pants (and wore a bun -- again!)

The reality starlet met (above) with reality mega-producer Nigel Lythgoe (American Idol, So You Think You Can Dance), and also took meetings about her new jewelry line!

Kim Tweeted, "Great meetings today! Just approved my new Belle Noel jewelry collection and its sooo fab!!!! Can't wait to do a fun giveaway!"

And while Kim, 31, kept busy, new hubby Kris Humphries, 26, had nights out this week with Jersey Shore's Vinny Guadagnino, 21.

The duo hit STK in Los Angeles on Tuesday -- they first got close after meeting on a plane last week. While Kim slept, they bonded, with Kris Tweeting: "This is the first time I have tweeted while in the air. Kim is knocked out next to me and I'm so bored I need to be entertained! ... Ran into @vinnyguadagnino 2 times one week. Vegas here we come!"

Such nights out are only fueling the fire that Kim and Kris are having marital problems. Reportedly, Kim is sick of Kris' partying (and flirting) and wants him to get to work. But, Kris argues that the NBA lockout is keeping him from being productive and says he's sick of being filmed all the time for Kim's reality show.

They married in August after only about nine months together.

And on Thursday, reports surfaced that the entire relationship might have been simply a casting decision from the start -- one site claims that E! was husband shopping for Kardashian.
