Khloe Kardashian: "Kim is at her weight goal, I'm not"

Kim Kardashian posting a photo of herself and sister Khloe in bikinis on her Twitter -- including Khloe, surprised many people.

"Honestly, I didn't even know Kim had Twittered that photo," Khloe, 25, says on Wednesday's Daily 10 on E!. "I was like, you didn't even ask [if] you could twit-pics a bikini photo of me!"

29-year-old Kim is nothing but happy with how her body appears in the snapshot (taken during the sisters' QuickTrim commercial shoot).

"I really feel like I have reached my fitness goal and now I am toned, fit and at a healthy weight and I just need to keep it up," she wrote on her website Monday.

Khloe Kardashian says she's not quite there yet herself. "Kim is at her weight goal," she says. "I'm not."

Then, should his new husband Lamar Odom be blamed? "I've gained a little love weight," she admits. "But I know by this summer I will have my ultimate bikini body. But I'm still happy!"

Indeed, the newlywed gushes, "it's just so natural for me to be married. I was never somebody who was a serious relationship person. Now I'm all in and it's so easy."

The couple is preparing to move into the nearly $4 million home in Tarzana, California after months of living in a hotel. Right now, she says "we're at a loft," where she's working on prepping homecooked meals for Odom. "Being here is helping me to prepare!"
