The '80s popstar will reportedly be among the contestants when the Channel 5 reality show returns for its next series.
A source told the Daily Star: "Producers have wanted her to go into the house for years and they've finally convinced her to do it."
Sam has been through some tough times recently, after she lost her partner of 16 years, Myra Stratton, to cancer in 2015, but she is reportedly now feeling ready to take on a new challenge.
"Sam has had a really hard year but she's a strong woman," the insider continued.
"She knows 'Celebrity Big Brother' is going to be tough mentally but she's ready to tackle it head on."
Sam is no stranger to reality TV, having previously appeared on 'Celebrity Wife Swap' in 2008, and 'I'm A Celebrity... Get Me Out Of Here!' in 2009.
Other contestants rumoured to be taking part in the new series of 'CBB' include Union J member Jaymi Hensley, ‘Mob Wives’ cast member Renee Graziano, 'X Factor' reject Chloe Mafia and 'Gogglebox' pair Stephen Webb and Chris Steed.
The 'Big Brother' house is currently full of civilian housemates, but the 17th run of the regular series is due to come to an end later this month.
