While the ladies are no stranger to the spotlight, a source told Us Weekly that the sisters 'were pretty reserved' on stage after 50 Cent invited them up.
'They just hugged 50 and Khloé waved to the crowd. Kourtney grabbed Khloé's hand [and] they shook a couple of the other guys’ hands,' the source said.
Kourtney and Khloe, who were seated with Victor Drai, the owner of Drai's, were among the countless stars to have flocked this weekend to Las Vegas, where the Billboard Music Awards took place on Sunday.

During a lull from their festivities, the girls took a snap with Jennifer Lopez, who looked sexy as well in a tight leather number.
The night happened to fall as the latest episode of Keeping Up With The Kardashians aired, a show which saw Kourtney ask her mother Kris Jenner for her opinion on her body.
While posing in front of a floor length mirror in a crop top, the reality star asked Kris, 'Mom, do you think my stomach looks wrinkly? Like an old lady stomach?'

Examining her reflection, she adds, 'And does it look better if it's sucked in or not sucked in?'
'Well it always looks better - ' Kris begins just as her daughter comes to the conclusion herself.
'No, not sucked in is better.' Kourtney declares.
'Hmm,' Kris adds.
