Myleene and Noel were spotted cheering on Suzanne from the crowds and even made a banner for the 32-year-old as she performed with professional skater Matt Evers.
Suzanne, who is taking part in the 'All Stars' ice skating special, impressed judges with her routine to Lady Gaga's 'Applause' on Sunday night (19 January).
An excited Suzanne tweeted before the show: "So looking forward to @KlassMyleene + @TheNoelSullivan coming 2 @dancingonice + the hearsay kids get to sit together! YAY X."
And it appears Noel got some practice on the ice himself, posting a photo to Twitter which showed him skating around the rink.
Suzanne was voted through to next week's show after impressing the judges and public with her routine, leaving former EastEnders actor Todd Carty to exit the competition.
Suzanne was in a celebratory mood after finding out she was through to next week, and joined Myleene and Noel for some drinks.
The trio were all smiles as they posed for a group photo. Captioning the snap, Myleene said: "Me @thenoelsullivan and @suzanneshaw on a #littlereunion."
Meanwhile, 33-year-old Noel praised Suzanne's skating efforts on Twitter. He said: "The best night at #DOI so proud of @SuzanneShaw she deserves the world."
Hear'Say rose to fame in 2001 after being created on ITV reality show Popstars.
The group - which consisted of Noel, Myleene, Suzanne, Danny Foster and Coronation Street actress Kym Marsh - achieved huge success with their debut single 'Pure and Simple', before splitting in 2002.
After seeing pictures of the Noel and Myleene with Suzanne yesterday, fans began speculating as to whether they would reunite and sign up for The Big Reunion, but Noel simply replied, "no."
