Alex said: "We have a surprise, we rang Pauline Black and she wanted to send you this message."
In the clip Pauline, who found fame as the lead singer of ska band the Selecter, showed her appreciation for Gwen's support.
After the video, Gwen said: "I could cry, zoom in guys this is real tears, wow I’m shaking.
"I can’t believe that, that is incredible."
Jermaine then said: "I can understand why."
But Gwen then quickly fired back saying: "No, you don’t understand anything!" as she waved her finger at him.
Jermaine didn’t know what to do as the rest of the studio started laughing.
Alex said: "You tell him Gwen!"
As Gwen added: "She was my idol when I was 13."
