We spotted Kim Kardashian and Kanye West holding hands as they left their hotel in London today. Kim looked lovely in a navy blue dress with spaghetti straps, while Kanye wore a white blazer, t-shirt and leather pants.

Last night the couple went to Zuma's in London with Rob Kardashian and his R&B singer girlfriend Rita Ora. Are things getting serious between K and K?

Season seven of "Keeping Up with the Kardashians" launches on Sunday, and E! just released the trailer. It features Kourtney's second pregnancy, Kanye and Kim's burgeoning relationship, practical jokes on mom Kris, Lamar Odom's lifechanging plans, and more Kardashian crazyness.

We can't help but wonder if Kris Humphries is glad he escaped it all.
