He said in a recent interview: "Yeah, Proudlock hooked up with Lucy and everyone knew and I was the last to find out.”
Jamie found about about the romantic trysts after he confronted the budding couple during Mark Francis’ boat party in Made In Chelsea’s NYC season finale.
He told Yahoo Celebrity: "I know I’ve done it in the past to Spennie but if you hook up with your mate's ex chick you go and tell them like a man and he just didn’t say anything and I had to find out, which kind of sucked."
"Also, I’m very protective and territorial with my relationships. Yeah, it’s quite sad. It hurt, it really hurt.
"But with all these things you just have to get over it, you can’t lose mates over girls.”
Awww, poor Jamie Biscuits… Hopefully he can salvage his friendship with Prudders!
