Scott Timlin, a 24-year-old nightclub promoter, and 19-year-old Outward Bound Instructor Daniel Thomas-Tuck will join the likes of Gaz Beadle, Charlotte Crosby and Holly Hagan when the MTV show returns next month.
Timlin, who has never seen Geordie Shore before, describes himself as "the life and soul of the party", claims to have "pulled more than Gaz without being on TV" and pledges to bring "more sex" to the show.
"Gary says he has a degree in pulling women; well I've got a PHD," he boasts. "He's got competition for the birds with us single lads coming in this series.
"I'm already famous in Newcastle... I walk into a club and 300 people shake my hand."
Thomas-Tuck, meanwhile, admits to being a massive Geordie Shore fan - so much so that his nerves at meeting the rest of the cast saw him act like "a massive tool" on their first night together.
"I'm quite loud and I can be a bit irritating when I'm drunk, but I don't care," he explains.
Unlike the other boys in the house, he claims he will not simply "bang anything", saying: "I'm picky. I've had opportunities to get with girls and I turn them down."
The pair replace departed Geordie Shore cast members Jay Gardner and Rebecca Walker, who left after the third series 'Chaos in Cancun' earlier this year.
Geordie Shore series four begins Tuesday, November 6 at 10pm on MTV.
