The Liverpool footballer faced the wrath of head chef Marco Pierre White, after he approached the pass while Abbey was busy.
Turning Peter away, Marco asked abruptly: "Excuse me, can you come back in 10 minutes?"
Peter returned to a table that he was sharing with Abbey's family members, but he returned to the pass later in another attempt to speak to his sweetheart.
Marco told Abbey: "If you want to go and say hello to him go and say hello to him, he's not allowed in the kitchen though! Just over the counter."
Clancy seemed happy to see Peter, informing him that he looked "gorgeous" and she missed him.
Speaking later in the confessional, she admitted: "When I saw him I thought I don't want him to be here! At first I was a bit shy and thought he would put me off but it was really good to see him. We spend every day together so its quite hard to be away from him."
Hell's Kitchen continues at 9pm tonight on ITV1.
