The Geordie Shore star, 26, will join 23-year-old Dan Osborne, who is returning after a successful stint with the male strip group last year.
TOWIE star Dan and Gaz will go head-to-head – both will have 10 separate tour dates, in a race to see whose nights can sell out the quickest.
Gaz said of joining The Dreamboys: “I’ve heard a lot of very good things about The Dreamboys, so when I got the call to be part of it I jumped at the chance.
“I mean, let’s be honest, I’m certainly not known for being shy and I think I could show Dan a few moves or two. All of the lads are proper nice guys, the only thing I’ve got to work on now is my physique as The Dreamboys are in incredible shape and have some of the best physiques I’ve ever seen.”
“I’m excited to be joining the 2015 tour, I think it will be a good laugh and I’m looking forward to meeting the fans – it will be like having my own party every night.”
On returning Dan said: “Last year was great, the boys are always good fun and the fans love the show. Why wouldn’t I want to do it again?”
The Dreamboys will embark on a massive 73-date tour this year, kicking things off in Plymouth on Friday 6th March.
