In our sartorial fantasies, Britney Spears and Kim Kardashian are best friends who go shopping together -- we love the idea of them teetering down the sunny streets of L.A., their small dogs in tow, buying matching outfits and giggling as they tweet to all their fans.

While we're not sure if they are actually shopping buddies, it might explain why the two were spotted wearing the exact same Herve Leger by Max Azria creation this weekend; Spears wore it to KIIS-FM's Wango Tango event in L.A. to promote her tour, and Kardashian was caught by the paparazzi while dining with boyfriend, Kris Humphries's, at Miami hotspot Zuma.

The pop singer toughened up the $1,450 frock with black stiletto boots, but the reality TV star kept her look feminine and pretty by pairing the dress with patent leather and mesh slingbacks made by Fendi.

No word on whether the two were texting all night or planning their next outing to buy matching outfits.
