She's got a lot of fabulous French meals to work off!

After returning from a romantic trip to Cannes with beau Kanye West, Kim Kardashian made a mad dash to the gym in LA, on Saturday afternoon -- she's gotta get that booty bikini ready, after all!

In other news, it's recently been reported that the reality star is setting her sights on a move to London to set up the first international Dash boutique, and to take a break from Hollywood for awhile.

UK's The Telegraph quotes Kardashian as telling BBC Radio One, "We would love to set up a D-A-S-H store in London and we were talking about who would take what city and London was one of the options. We don't spend a lot of time here, so it would be fun. It's like our dream."

The Kardashians are also considering taking their reality show to London, and basing the plot around Kim and Khloe opening up their boutique there.
