The hideously annoying Pete Wentz hosts “F N MTV” that premieres with Heidi Montag and Spencer Pratt as guest stars. Heidi Montag and Spencer Pratt “act” themselves in “F N MTV”.Says MTV about the show:“In an ambitious attempt to put the M back in MTV, the network is launching a new Friday night music show aptly titled F N MTV (premieres June 13 at 8pm). And who better to represent the hope, genius, and hard work behind this project? Madonna? Mariah? JT? Sorry, they were busy. But luckily, Speidi had some time on their hands! And they were willing to poke a little fun at themselves… all in the name of sweet, sweet music. In the below show promos, watch Spencer as he, um, watches himself.”
