'Kardashians' Roundup: Sisters Flaunt Their Bikini Bodies and Dash Nudies
Sometimes, we just can't help but wonder if the Kardashians ever get tired of showing themselves off. But when we come upon these sorts of news, we get the answer pretty quickly: no, they never tire, they just really love self-promotion.

Keep Up with the Kardashian's Endorsements

Read on to find out the latest flaunts of the Keeping Up with the Kardashians stars.

Kim Boasts New Bikini Body
Now that her ex Reggie Bush is preoccupied, Kim Kardashian has a more time on her hands to work out. She revealed her post-breakup look to Life & Style magazine and said, "I really wanted to just buckle down and get rid of the tiny bit of excess weight I was carrying."

The Keeping Up with the Kardashians starlet added, "I work out to feel good about myself -- and sure, it doesn't hurt if someone notices."

Well, she did grab the attention of one rising artist:

Justin Bieber Reveals Krush on Kim
If the 29-year-old Kardashian sister can't get her mitts on any other NFL running backs, she may want to try getting to know Justin Bieber. He is, after all, smitten by her.

The singer told MTV UK, "I can pick any girl... I'm gonna take Meagan Good. I'm gonna take Kim Kardashian. And Beyoncé."

As we expected, the reality TV starlet heard about the news and sent her own message to Bieber. Kim wrote on her Twitter account: "Amazing how @JustinBieber is a trending topic everyday! I have Bieber Fever!!!"

We won't be shocked if Kim Kardashian ended up with the most unlikely of fellows, especially since her ex was spotted with another lady recently. The Hollywood Gossip reports that Reggie Bush was seen with Jessie James, the country singer.

They were spotted in Vegas last weekend, which is probably why Kim took it upon herself to lose five pounds in five days. But if she's hoping to get even more attention, we suggest she imitate her sisters.

Kourtney and Khloe Strip for Dash
Among all the possibly airbrushed photos that the Kardashians have of themselves, the latest to literally hit stores is the nude shot of Kourtney and Khloe. The photo, posted on their official blogs, depicts the sisters and a couple models baring it all for Dash. Well, sort of.

"Kourt and I came to Miami to revamp Dash, and that's exactly what we did!" Khloe wrote. "It literally took ALL day to get airbrushed but it was so worth it."

As for Kourtney, she shared the excitement. "Khloe and I needed a fun way to let everyone know that we revamped Dash Miami. This was our way! We came to town and made the store better than ever."
