Eamonn and Ruth Langsford spoke to caller Jessica, who was thrilled to have been picked by the pair.
However, she thought she was speaking to Holly Willoughby and Phil and Eamonn wasn't happy.
Jessica said: "Are you kidding me? I'm really talking to Phil and Holly?!"
Eamonn replied: "No you're not talking to Phil and Holly.
"Better than that! Cancel her and move on! Next one!"
Jessica said: "Oh is it Eamonn and Ruth? Oh my god! Oh my god!"
Jessica told the hosts she was on maternity leave and was on a walk around the park with her baby.
Eamonn then spun the wheel and Jessica won £1,000.
She exclaimed: "One thousand? Oh my god! You've made my day.
"It's amazing talking to you guys. Thank you so much!"
Cancel her and move on! Next one!
Jessica then asked: "Do I have to stay on the line?" to which Ruth said: "You can if you want!"
Jessica added: "I mean how does it work?"
Ruth told her: "Don't worry, you stay on the line and someone will explain to you how it all works."
Viewers were in hysterics listening to Jessica's call.
What did viewers say?
One person said on Twitter: "Aww I love how excited Jessica is to be speaking to Eamonn and Ruth."
Another wrote: "Haha Jessica is obviously not watching saying Phil and Holly."
A third added: "The spin to win caller to Eamonn & Ruth: 'Oh my god I can’t believe I’m talking to Phil & Holly!'"
