However her Big Brother appearance has nothing on when she starred in Coronation Street.
Sarah came to blows with none other than Tracy Barlow when playing Robert Preston’s wife Joni.
The scene, which aired in 2015, saw Joni turn up to Robert’s restaurant just as he embraced Tracy for a kiss.
“Let me Guess, Tracy Barlow?””
While walking in, Joni was heard saying: “I felt awful leaving you to clear up like that.”
However, her mood song changed when she saw Robert and Tracy are mid-snog.
She scathingly asked: “Let me Guess, Tracy Barlow?”
A confused Tracy replied: “Yeah, who are you?”
The blonde explained: “Joni… his wife,” before slapping Tracy straight in the face.
Wowsas, we must warn Chad not to mess with Sarah.
