The TOWIE hottie looked virtually unrecognisable in his spooky costume as he arrived to film the show's Day of the Dead-themed party on Tuesday, 27 October.
Pete opted for Beetlejuice-esque striped trousers and a bare chest (to many fans' delight!), which was covered with fake slashes and blood.
His make-up was pretty impressive - like we said, we almost didn't know who it was... although the big blue eyes do give it away!
The whole The Only Way Is Essex cast have really got into the spirit for the Halloween-themed episode. We brought you pictures of Jess Wright, Georgia Kousoulou and Tommy Mallet's incredible costumes earlier.
Meanwhile, on tonight's episode of TOWIE, we'll get the latest on what's happening between Pete and Jess in their will-they-won't-they relationship.
TOWIE airs Wednesdays and Sundays at 10pm on ITVBe.
