Celebrity Shopping Guide

By Melissa Hunter

Star endorsements are a long-standing celebrity tradition, so it's no wonder that the market has evolved into celebrities designing and launching products everywhere we look. In our Celebrity Shopping Guide, we break down the latest and greatest A-list products. Sorry, no coupons.

Get 'em while they're hot! Will Ferrell launched a new sunscreen (in Sexy Hot Tan, Sunstroke, and Forbidden Fruit varieties). The proceeds will go toward Cancer for College, an organizaton which gives scholarships for cancer-stricken teens who want to go to college. Ferrell, in turn, can cross-promote his new film about a guy who launches a sunscreen brand, gets drunk, does some stupid things, and hilarity ensues. Well, he's not filming it yet, but surely someone is working on that one.

For her latest feat in obnoxious hipsterdom, Mischa Barton is launching a headband collection with designer Stacey Lapidus (strictly for over the forehead use). The hair accessories range from the bargain prices of $50 to $200. Regarding her style and inspiration, she says, "My style has been somewhat boho chic, which I think is a result of having traveled so extensively throughout the course of the year." First of all, how boho-chic relates to international travel is unclear. Sounds just like an obnoxious 20-year old who comes back from their junior year abroad in France as a beret-wearing chain smoker with an accent.

In a recent radio interview, Lily Allen has announced her plan to launch a jewelry line. The fashion-forward singer previously designed a line of prom dresses, so naturally she'll need to give those teen Lily wannabes some accessories to match. The line should be due out by "the back end of this year" (that's British for December). Though after a recent accident on-set, we think she should be more inclined to design some anti-nipple-slip tape. If not her, can someone PLEASE design this already for all of our nip-blivous starlets?

Paul McCartney and Ringo Star have been publicizing the new Beatles Rock Band Video Game. The game wll have replica Beatles instruments and the long-awaited remastered Beatles catalog will be released the same day (what a coincidence!). McCartney muses, "We never thought we'd end up as androids!" Well that makes one of us. Clearly he hasn't been reading about the post-Twitter-celeb-robot-apocalypse theory. In any event, the game sounds friggin' sweet.

What do you get when you combine Miley Cyrus, Max Azria, and Wal-Mart? Yeah, we don't know either. But we'll soon find out. Miley and Max Azria are launching a junior clothing line to be released in Wal-Mart this summer. With Hannah Montana hysteria everywhere, we're hoping Wal-Mart security is in training for launch day to prepare themselves for the biggest tween stampede the world has ever seen.

Bar Refaeli was pretty much born in a bikini, so it's only natural that she would try her hand at designing one herself. She recently designed one for Hurley, saying "I am obsessed with finding the perfect little black bikini." I'm guessing pretty much any black bikini is the perfect black bikini on Bar. But this didn't stop her from setting out on this noble quest to create the ultimate black two-piece. At $120 a pop, there better be a "get an A-list celebrity boyfriend or your money back!" guarantee.

In a much trashier swimwear store across town, Heidi Montag has designed a line of bikinis with Ashley Paige. She said she'll be wearing them on her on-again-off-again show "I'm a Celebrity…" and will then going to Miami Fashion Week. "So you'll see me in more bikinis than ever before!" says Montag. Oh, phew. Here I was staying up nights worrying about endangered Heidi Montag bikini shots.

"Top Chef" judge Padma Lakshmi is set to launch a jewelry line. Sold exclusively at Bergdorf-Goodman, the line of necklaces, rings, cuffs, and earrings have shapes inspired by food. Retailing between $300 and $6,000, I would only hope the inspirational food is strictly foie gras and caviar. Coincidentally, she shares more than just an affinity for shiny objects with her fellow jewelry designer Lily Allen. She also fell victim to the nipple-slip epidemic at the White House Correspondents' dinner. Perhaps a love of bling is inversely proportional to a love of bras.

Newly indie Hilary Duff is slated to launch an "edgy" clothing line with DKNY. Described as a "downtown cool" line, she says she's inspired by "normal girls." Well, that's a refreshing notion. She tells Nylon that it's "kind of a selfish line, because it's skinny jeans, which look the best on me." You know what, Hilary? It's your design party and you can make skinny jeans if you want to.

No matter how hard we try to will it to happen, this woman will not disappear or be forever banished to a planet where cameras and fertilization drugs do not exist. Kate Gosselin reportedly plans to start an affordable clothing line similar to Jaclyn Smith's line for K-Mart. If her hairstyle is any indication, we'll surely see the klassiest clothing line K-Mart has ever seen. A source tells Star, "She's trying to brand her name and build a Kate empire." Super. Now I'm going to have Kate empire nightmares.
