The awards were met with a surprising moment when a scantily clad Sadie walked in between Ant and Dec as they were presenting the next segment of the live music ceremony.
Sadie tried to steal the limelight as she stood in the middle of the two presenters and showed viewers her full outfit - from the front and behind.
Sadie wore a transparent, sheer catsuit with black panels and not much else. Her outfit is said to have been inspired by the Brit Award and was designed by Pam Hogg to wear at the ceremony.
Poor Ant and Dec didn't quite know where to look and viewers took to social media to share their confusion.
Television watchdog Ofcom are now "assessing whether to investigate" after receiving more than 50 complaints.
Meanwhile, Sadie told The Sun: "I only decided to do it five minutes before, but I know them and I asked Pam. I thought, 'As long as she says it's okay, I'll do it.'"
