When in Vegas!
Khloe and Kourtney Kardashian got the VIP treatment in Las Vegas on Sunday, where they were spotted partying it up with Jennifer Lopez, Meghan Trainor and Jessica Alba (below) at Lopez's Vegas show, before heading to some more Billboard Music Awards' parties.
Khloe shared some photos from the night, where she and Kourt showed off their hot bods in matching revealing black numbers. "Bow down to the queen @jlo," she posted with one group shot from the festivities.
Following the "Booty" singer's concert, the "Keeping Up with the Kardashians" stars headed to 50 Cent's Billboard Music Awards after-party -- held at Drai's Nightclub -- where they were pulled on stage by the rapper himself during his performance of "P.I.M.P.".
According to Us Weekly, Khlo and Kourt seemed a tad timid on stage, simply waving to the crowd and giving the "In Da Club" rapper a big hug before making their way back to their table.
It definitely looked like both sisters had a blast! What do you think about their Las Vegas appearances? Sound off below and check out the gallery above to see more behind-the-scenes photos from the Billboard Music Awards!
