So far, our Spring Break With Grandad party animals (and their equally as wild grandparents) have been partying hard enough to break a limb or two, eager to impress a mystery judge who, for all they know could just be a rogue computer spewing out random names to go home each week.

This week though, the Spring Breakers are in for the BIGGEST SHOCK EVER, as Geordie Shore party legend Gaz Beadle enters the house to reveal himself as their judge, and to join in the Cancun party.

WATCH GAZ'S SHOCK ARRIVAL HERE:

And he's already promising to take things to a brand new level.

OI OI, LAD!

Speaking before entering the Spring Breakers luxury pad, Gaz says: "I party for a living. They've got no idea what is in store for them. This is go hard or go home.

"You don't have two shots, you have ten. You don't sip your drink, you neck your drink. In Newcastle that's what we do and they're gonna sh*t themselves."

Of course, Gaz has also brought his 'hero', his grandad Raymond, along for the party, who admits that he has just a little idea of his grandson's partying ways.

He admits: "I think Gaz can take the partying to another level, no problem at all. I've got a fair idea what goes on (in Gaz's world), and I'll write it all down and tell (Gaz's) mum."

Better behave yourself, Gaz!

It's then time for the Geordie radgie to make his surprise entrance, creeping into the house and announcing his arrival by popping champagne on one of the balconies. A subtle entrance, obvs.

The Spring Breakers are obviously pure shocked to see Geordie royalty in their humble abode - although the grandparents weren't *quite* so excited, with Andy admitting: "Gaz has just walked in - I don't know who the f**k he is!"

Finally explaining his reason for dropping by unexpectedly, Gaz tells the party animals: "The reason I'm here is to take things to a whole new level."

'WHY AYE! But will our Spring Breakers take on the challenge with both hands? Who will be the next to fall at the Sambuca shot hurdle? Find out as Spring Break With Grandad continues, TONIGHT (Monday 27th February) at 10pm - only on MTV!'
