Kendra Wilkinson has always been open about her body, but it seems like lately, her assets are giving her trouble. "I think my right butt cheek is bigger than my left butt cheek," the Kendra star tweeted Tuesday to her 1.8 million Twitter followers. "Oh and my right boob is sooo much bigger than my left boob. I'm so off. Lolol," she added in another tweet. But despite her willingness to bare it all, the 26-year-old (who is married to NFL free agent Hank Baskett, with whom she shares 2-year-old son Hank Jr.) admits that there have been certain moments where her modest, more conservative side takes over. PHOTOS: Aw! Baby Hank's cutest moments "To tell you the truth, whenever I used to pose for Playboy I used to get so, so scared and I used to cover up and I'd be like 'hurry up!'" the former Girls Next Door star said in an interview with news.com.au in October. "I was very proud, but at the same time I never got used to being naked. I never did and I will never do it again."
