After bitching about her weight and hitting the gym on Tuesday morning, Kim Kardashian went to the Westfield Topanga mall near her family's compound for a little shopping spree. Maybe she saw our photos of her big ol' booty from Jimmy Kimmel last night? Her derriere was looking significantly rounder than usual, so we kinda get it. But if she's trying to drop 20 pounds, maybe she should wait a few months to update her wardrobe? Just a thought!

Around 7:40am, Kim tweeted:
    "off to an intense workout. Can't seem to shake this last 15-20 lbs of baby weight. no more excuses. my baby is 1 years old! UGH I'm not gonna call it baby weight bc thats an excuse. i just gained weight & that's it. why is it so much harder to lose after baby though!! do any of u moms see their bodies just not the same? a different shape? ughhhh my hips & butt are huge now! they were big to begin with! Just need to get down to my weight a few years ago.

    Not gonna complain anymore. Starting diet TODAY! No carbs. crazy workouts. Whos with me? i think after having a baby u get so excited u lost a lot of weight then u get comfortable & eat how you used & it creeps back up. ok no more tweeting and procrastinating! LOL Glad some of u moms can relate. I'm reading the comments! For real....of to the gym! wish me luck on the dieting...its soooo hard for me!"

Aww, poor Kim. We know how hard it is to eat healthy and exercise when you have tons of free time and millions of dollars to spend on personal trainers and nutritionists. Oh wait! We actually don't. We just bust our butts at the gym and don't stuff our faces every time we sit down for dinner -- and we certainly don't gripe about it!

Maybe she's just extra whiny lately because she's missing hubby Kanye West? He should be coming back from Singapore soon...
