Lockie made the jibe while chatting about his BFF in a new video interview, insisting that Pete "has changed" since falling for co-star Megan McKenna.
When asked by his pal Tommy Mallet whether "Megan has changed Pete", Lockie replied: "Yes. 100 per cent. He's no longer like, got a bit about him. He used to be Pete The Pirate. He had a bit about him, he was feisty. Now he's Pete The Plum."
Earlier this month, Pete and Megan posed for a SERIOUSLY racy naked selfie while on holiday in Barcelona.
After posting it on Instagram, Megan has defended the photo, insisting it was "PG". However this hasn't stopped their co-stars from talking!
Chloe Sims definitely found it amusing, but what does Lockie think?
"I wish I was there!" he joked, during the TOWIE Facebook video. "No, truthfully...I think it has just taken selfies to a whole new level."
Meanwhile, during his chat with Tommy, Lockie also opened up about his breakup with Danielle Armstrong, saying that they are both "hurting".
