Fasten Your Seatbelts! Inside Rihanna's Wild Jum-Booze Jet

Ready for lift-off? Rihanna certainly was during a recent flight stocked with supplies to ensure that she didn't have to fly the sober skies. The hard-partying singer gave fans a glimpse inside her private bar at 35,000 feet on Instagram Monday night.

En route from New Zealand to her next show stop in South Africa, the "Pour It Up" singer was doing just that as she made her way across the world.

"Can't tell if Rihanna's assistant @jennnrosales is more geeked about the personal minibar, the 130-year-old Hennessy on the bar menu, or the lounge bar sitting in the middle of the plane drinks free all flight!" the singer bragged.

RiRi then posted a picture of her own personal light-up mini-bar, as well as a full glass of champagne resting on the vanity at her seat.

All impressive, but potentially worrisome for fans who have seen Rihanna's partying take a toll on her Diamonds World Tour, which has been plagued by delays and lackluster reviews. Indeed, several fans criticized the singer's drinking habits in the comments section of the photos.

A reviewer in Perth accused her of being "glassy-eyed" and boozed-up during a show on September 24, for which she arrived nearly 90 minutes late.

Before that, fans accused her of "high on weed" and "lip-synching" during her September 22 show in Singapore.

The European leg of the tour earlier this year was rife with similar accusations of drug and alcohol abuse.
