That was fast: In March a casting call went out for socialite Tinsley Mortimer's reality show, and apparently MTV has already shot — and rejected as too boring — Mortimer's show. According to Page Six, the cable network's producers, who by this point are surely experts in whipping up drama from the barest of reality TV ingredients, couldn't make anything of the footage: "She looked good but she just got dressed and went to parties every day and didn't have anything interesting to say," a tipster told the Post. Uh, right, because reality television is all about stimulating conversation, and Mortimer was hired for her intellect. Translation: She didn't get into any brawls, do enough drugs, say anything racist or have a sufficiently interesting sex life. The show getting cancelled is a no-lose situation for Mortimer. She either takes it happily in stride or has gigantic breakdown that brings back the reality TV crews and launches her into broader starletdom. [Post]
