Who Was Kim Kardashian's New Year's Eve Date?

Kim Kardashian spent her New Year's Eve at TAO in Las Vegas, and she partied the night away in a bedazzling with dress with her hot date -- her brother Rob! Yep, she brought her baby bro, not her rumored beau Kris Humphries (that we know of), to the swanky club to ring in 2011.

Kim and Rob Kardashian (via Twitter) "Who's excited for the new year? Let's leave the past behind us and move forward! Do better and push yourself in 2011!" she wrote on her Twitter page before the festivities got underway.

Later in the evening, she posted a pic of herself and her "New Year's date," brother Rob, and then added another pic of herself sitting next to BFF Brittny Gastineau.

Kim was certainly dressed to impress, and sounds like she had a night to remember!
