Eileen Daly, who is a former adult model auditioned for last year's series alongside husband Ben Thirkettle as part of duo 'The Courtesans'.
The duo made it to the bootcamp stage of the competition before being cut. They now play together under the name 'Eileen and Ben' and have made appearances at festivals including the Bram Stoker International Film Festival.
Eileen is also an actress, who has appeared in a number of films (mostly as a vampire) although judging by the Rotten Tomatoes review for one of said films 'Razor Blade Smile', we're not sure she'll be giving Meryl Streep a run for her money any time soon.
At 51-years-old, Eileen is the oldest housemate to be entering the Big Brother house on launch night but given her past work with adult film producer Ben Dover, we can't see her having too much trouble keeping up with the younger housemates.
Big Brother 2015 kicks off Tuesday, May 12 at 9PM on Channel 5 with its new 'Timebomb' series.
