If you thought Lindsay Lohan's stint as the Lawyer.com spokesperson was weird, you ain't seen nothin' yet: Mariah Carey—she of lavish 5-star hotels only, dahhhling—stars in a new commercial for Hostelworld, an international hostel booking web site.

In the clip, the Elusive Chanteuse finds herself booked at a budget hostel (gasp!) when her assistant accidentally messes up her hotel stay arrangements.

After the singer pulls up in a limo and suffers a mini diva breakdown at the front desk in the lobby ("Deal with it!" Carey shouts at her handlers when they first walk into the hostel), the music icon eventually finds herself more than satisfied with the business's accommodations, which include a clean suite and pristine, private bathroom.

There's even a bar downstairs, which Mimi—decked out in a gold, shimmering gown—ends up in for an impromptu performance of her 1995 hit song, "Fantasy."

Watch the clip, below:

As for the collaboration, Carey said in a press release, "For some reason, someone thought it would be funny to book me in a hostel. To mine and everyone's surprise, the hostel was fabulous! It was super clean, modern and spacious. I say give hostels a go, it could be a great choice for all you world travelers out there."
