Avril Lavigne, Ludacris, Lauren Conrad And More Give Vegas Packing Tips For VMA Weekend

'Have your entourage with you at all times,' Chingy advises.

It might not seem so at first, but packing your bags for Las Vegas is a logistical nightmare. How many pairs of gambling shoes should you take? Do you stuff a copy of your birth certificate in with your toothbrush, just in case you’re in the mood for a quickie wedding? Should you bring large bills for bail, or do you go the Pacman Jones route and just fill a garbage bag with $81,000 worth of singles to make it rain?

Clearly, these are all very important questions, ones you probably haven’t answered yet. A properly packed suitcase is the key to having maximum fun in Vegas, and the last thing you want to be is ill-equipped for anything the town decides to throw at you. So to help you prepare for your fantastic voyage, we’ve turned to a panel of celebrity experts to find out what’s in their Louis Vuitton rucksacks when they hit Sin City.

From designer sunglasses and Speedos to comfy pajamas and condoms, here’s what the stars bring to have the time of their lives. (And you thought packing for Vegas just meant tossing some socks and skivvies into an old gym bag.)

(Watch Ludacris, Avril Lavigne, Bow Wow and more tell you what to pack for Sin City.)

Avril Lavigne: “Going-out clothes and sweats for being hungover the next day. And a bathing suit to go out to the pool and a really cute outfit for the next night.”

Lauren Conrad (“The Hills”): “Something with sequins!”

Audrina Patridge (“The Hills”): “Sunblock, lip gloss, eyeliner, hot clothes. Flashy, sparkly things. It’s Vegas — you gotta dress fun!”

Ludacris: “Usually when I go to Vegas, I hit the town as soon as I get there, so I don’t pack anything. There’s a lot of good shopping there, so I’ll just go pick something up. … But you gotta have some money in your pocket to gamble, of course.”

Jordin Sparks: “You gotta look cute, you gotta look good in Vegas, so … bring a couple of tank tops. Also, definitely bring your cell phone and your friends. And comfortable shoes, because there’s a lot of walking.”

Keke Palmer (“Akeelah and the Bee”): “I think you just have to have a banging outfit for the whole trip. … What you need to do is just go there with designer clothes and sunglasses and just do it up like you’re famous, even if you only have one dime.”

Chingy: “You gotta bring a 12-pack of Magnum [condoms], and have your entourage with you at all times.”

Emmy Rossum (“The Phantom of the Opera”): “Bring suntan lotion. You definitely need to bring suntan lotion.”

Sophia Bush (“One Tree Hill”): “When you pack for Vegas, you gotta have a great pair of shoes that are comfortable, because if you’re gonna be dancing to the DJs till the wee hours, the last thing you want to do is take off your shoes in a nightclub.”

Corey Haim: “I just bring sunscreen and a Speedo. No, clogs and a purse. [He laughs.] I’m not going [to Vegas] to gamble. … I prefer going to Cirque du Soleil.”

Bow Wow: “I keep my [American Express] Black Card with me, so all you other big rappers and ballers, you better come to Vegas with your Black Card. Believe that!”

Shop Boyz: “You don’t go to sleep in Vegas, man! You do not sleep. So basically all you need is money. That’s the number one thing: You gotta have money. You can get everything else there.”
