Khloe Kardashian has reportedly been acting like a ''real diva'' on her new reality show.

The 29-year-old star is said to have surprised the crew on 'Kourtney and Khloe Take The Hamptons' by repeatedly being late for filming and constantly complaining about their new location.

A source told ''Khloe has been showing up late for call times, and has offered no explanation for the delay.

''The crew has been left in the lurch because they can't get any work done until Khloe decides to show up. This is very atypical of Khloe, who previously would often turn up early for shooting!

''Khloe has been complaining about being in the Hamptons, and doesn't understand why the locals are so angry about their arrival in town. She is acting like a real diva, and says the Hamptons should be lucky to have her in town, as it's a boost to the local economy.''

According to the insider, Khloe's family are laying the blame for her attitude with new boyfriend French Montana - who she began dating this spring, months after splitting from husband Lamar Odom - and her sister Kim Kardashian and stepfather Bruce Jenner are convinced the 29-year-old rapper is ''using her for fame''.

A source said recently: ''He's eager to sit at the cool kids' table and has been trying to get close to people he thinks are popular..

''Being with Khloe means everyone knows who French is now, so he's getting a lot out of it.''
