“I’m ageless,” she exclusively tells PEOPLE. “I feel great. I’m healthy, working out, and happy. I’m basically Benjamin Button!”

Singer and her fellow Housewives, who arrived on Thursday, will be enjoying a luxurious vacation in the city that never sleeps until Sunday.

Staying in 2,400-sq.-ft. suite at the Encore, the women will be living it up with relaxing hikes, massages, brunches and, of course, endless amounts of champagne.

To kick things off, Singer and her squad dined at Andrea at Encore. While there, the guests all wore blonde wigs to become the “Ramona’ettes.” To conclude the evening, the ladies headed back to Singer’s suite, put on silk PJ’s and enjoyed a good old-fashioned sleepover.

To top off the trip, the ladies are scheduled to see the ultimate Vegas show: Britney Spears!

Since her divorce from ex Mario Singer was finalized earlier this year, the reality star hasn’t wasted any time getting back into the dating game.
