The 'Wow' singer - who has spent years trying to crack the US - has been offered a residency in the city after impressing American fans with her recent tour.
Kylie's sister Dannii revealed to Britain's Daily Mirror newspaper: "The response from her shows in America have been phenomenal. They love her out there. She was nervous about going over for the first time, but it has gone better than she expected.
"She has now been asked to take the show back to Vegas and extend it as a residency over there. I'm so proud of her."
Las Vegas promoters were mesmerised by her glamorous show and are convinced she can draw in the crowds night after night.
Dannii says Kylie is thrilled by the offer and she will be supported by her family on her opening night.
She said: "Kylie called to tell me how well everything has been going and about the Vegas offer. I was joking with her that is finally where she belongs!
"Kylie's show is perfect for Vegas, it's so theatrical. She has loved performing out there."
