I am entering the third week of my Nivea 'Goodbye Cellulite, Hello Bikini' challenge and I have kicked up my fitness and nutrition plans and I totally see a difference! I have been using the Goodbye Cellulite cream and patches and can really see a difference already! Good luck to everyone doing the challenge with me! Check out my pics from behind the scenes at the Nivea Challenge launch barbecue in Malibu.

Guys, don't forget that my Fit in Your Jeans by Friday Challenge is running until June 11 so you still have some time to submit your photos. All you have to do is pick one of my Fit in Your Jeans by Friday DVDs, workout for a week and send me your before and after pics of you in your jeans on the Friday. You can email your pics to kimkardashianchallenge@gmail.com. More info and pics of Valerie, Brooke and Shante, who all completed the challenge, can be found here.

This last Sunday I attended a fun barbecue in Malibu to kick off the summer! We launched the Nivea 'Good-bye Cellulite, Hello Bikini' challenge. Now I am in week two of the program and it's going well. I have a lot more energy and feel motivated to continue. You should have seen how amazing these Shay Todd bikini's were at the bikini bash! Are any of you doing the challenge?

I've always been very comfortable with my curves. I feel lucky to have an hour glass shape and I hope young girls can look up to me as a curvier woman, as opposed to idolizing unnatural body shapes that, for the most part, are unattainable. You all know I've been working hard this year to get in shape, while maintaining my curves. I work out every day (and yes, I admit, sometimes I find it hard to eat healthy) but I'm really trying, more than anything, to stay healthy. I think there's a big difference between being healthy and being skinny. If anything, sometimes being too skinny is a sign of being unhealthy, and that is SO not me. But like any girl, I'm always looking to improve myself physically, so when I heard about Nivea's new challenge, I thought it might be worth a shot. The challenge is called 'Goodbye cellulite, hello bikini." Yes, I have cellulite, but like any other woman in American, I would love to NOT have it. So why not take up the challenge!? It's not a quick fix, the challenge involves a product, fitness, nutrition, skincare and style regime that can help you get bikini-ready. I would love it if you guys could try it out with me, and we'll see together how 30 days can make a difference.

Just visit the Nivea website to sign up and find out all about the challenge.

If you came down to Kitson, Robertson on Saturday afternoon you may have heard all about my new fan challenge!! To celebrate the success of my workout DVD series, I've decided to challenge my fans to a Fit in your Jeans by Friday challenge! I've teamed up with Kitson boutique and am encouraging all you guys to put on your workout outfits, pop in your Fit in Your Jeans by Friday DVD and start working out! Just take a photo of your Monday jeans look (before the workout) and then another of your Friday jeans look (after the workout) and send them to kimkardashianchallenge@gmail.com to enter to win the grand prize drawing. I'll be picking out the winner from the entries and the best transformation will win a pair of sexy designer jeans from Kitson hand picked by me! So if you haven't ordered your DVD yet, make sure you do!

Valerie, Brooke and Shante (pictured above) each chose one of my three DVDs and worked out every day for a week! Take a look at the girls' working out with me in the gallery and check out their before and after pics!!!

Good luck you guys... and remember, have fun while you're working out!!
