Awww, how sweet of her.Khloe had a few more colorful tweets than that. (here) Thank you Khloe for putting words to the visual we already had. Kim looks amazing in that tight white dress, that Kanye West is a lucky dude. Kourtney isn't too far from having her second child with Scott Disick. I wonder if she'll go into labor while they film this season? The only way to find out is to watch the show. Keeping Up With the Kardashians airs Wednesday nights on the E! network.

But he insists that he will do better than Kim, who got kicked off in the third week. Rob told People:

"She expects me to do better than her, and I expect myself to do better than she did."

Good luck to Rob and Cheryl!

Could a baby be in Kim's future? An eyewitness saw her buying a pregnancy test earlier this month in Amalfi, Italy, while Kim was on her honeymoon with new husband Kris Humphries. The eyewitness told Life & Style:

"I saw Kim in the chemist. She came on her own and bought two pregnancy tests. She didn't speak any Italian and looked a bit embarrassed. The counter staff didn't know who she was, but we get Keeping Up With the Kardashians back home, so I knew that she was famous."

Don't expect to see a lot of Kim's new boyfriend, NBA player Kris Humphries, on the show. Kim wants to keep him out of the spotlight (unlike some of her past relationships). Her friend told Radar:

"Kim is really happy with Kris and just wants to have a more private relationship than she's had with past boyfriends.

"She not going to repeat what happened with Reggie Bush where things were so out in the open. Kim wants to keep things a little more quiet, she's a lot more mature."
