When dealing with a break-up, it's always nice to have people who you can count on to support you. For Kourtney Kardashian, she's got her sisters to help keep her mind off her recent split from Scott Disick.

Kourtney spent the morning working up a sweat with her sisters Kim and Khloe Kardashian. In the evening the trio hit the town looking absolutely angelic in radiate white dresses. It was Kourtney's first appearance in public since news of the split broke on Monday, and she looked like she was ready to have a fun night.
