Tonight sees the last episode of The Big Reunion, which features Eternal's three other members Easther Bennett, Vernie Bennett and Kéllé Bryan.
Louis declined to take part in the show, saying previously: "It was great, but I can't see the four of us ever reunited. I can't see us really doing it all again now."
However band member Vernie has claimed she's since met up with Louise and there are now plans for a full on reunion.
"I met up with Lou two weeks ago and she was really keen to do something," Vernie revealed this week.
After meeting up for coffee with Louise, Vernie said: "We got chatting and a reunion is definitely on the cards. We'll be talking more. It's very exciting."
Vernie told Now magazine this week she was hoping to get a tour together for the band after this year's official Big Reunion Tour line up was confirmed to be featuring only boybands.
"I thing it would be amazing for the fans, even if Louis was just involve with four or five songs," she added.
