Spencer Pratt and Heidi Montag are causing all kinds of tomfoolery behind the scenes at the Miss Universe Pageant, as the newlyweds prepare for Montag’s live singing debut at the event this weekend.

On Sunday, Heidi will to take the stage to perform her single “Body Language” during the event at the Atlantis Paradise Island resort in the Bahamas. Although the festivities haven’t even kicked off yet, a pageant insider claims the reality couple is stirring up trouble for pageant organizers and hotel staff.

“They’re a complete nightmare. Heidi has missed many rehearsals,” The New York Post’s Page Six column claims. “Spencer tried to demand that the hotel pay him to lay by the pool.”
