The Rumor Mill has gone into overload on who will be the new host of the Summer edition of Big Brother 2013, The is word on the street that current Host Brian Dowling who has been on the show since 2011 will be axed by BB Bosses. And there is a possibility that Big Brother's Bit on the Side Host Emma Willis could be stepping into his role as the main host, instead of the after party. Bosses are said to be considering a swap of shows for the two presenters, but insiders have said that Dowling is unlikely to agree to what would in effect be a downgrade. But would it be a good move? We know Emma has been there since big brother's bit on the side in the early days and host of BBOTS? but is she enough to be the main attraction. And will Brian be kept on as host?
