They're no strangers to the world of retail therapy, and yesterday (June 29) Kim Kardashian and Reggie Bush did some serious shopping.

Joined by gal pal LaLa, the "Keeping Up with the Kardashians" babe and her hunky beau checked out the Chanel boutique on Robertson Boulevard amidst a sea of paparazzi.

In related news, Kim helped her sister Khloe celebrate her birthday over the weekend with a trip to Las Vegas with their friends.

On her official site, she wrote, "Khloe's 25th birthday in Vegas was nuts! We started the night off at Spago restaurant then headed over to the club! Pure is always the best time! Me, Reggie, his friends, Khloe, Rob, Kourt, Monica, Brittny, Lala, Robin, Mike, Jonathan, the whole crew came out to party with us!"
