Last night (11PM US Time), HSN (an american shopping channel) had a BTS exclusive of the making at cheek to cheek

she's basically selling the album the entire time, while you watch the recording sessions
While the show was on air they received 15,000 orders for the album, it airs again in a few hours
the bitch keeps reading tweets throughout the show and all the @'s have monster in the name, i think she thinks they're casual people watching the show
