The pair are tipped to be axed over fellow nominees Deana Uppal and Adam Kelly in tonight's (August 10) live show, which comes a mere three days before the final.
Ashleigh is by far the most popular choice for eviction with odds of 2/9 from Paddy Power, while Scott is just in front of Deana with odds of 5/1 to the Miss India UK's 8/1.
Adam is an outside tip for eviction with odds of just 14/1.
Luke Anderson and Sara McLean are already through to Monday's (August 13) final after receiving the fewest nominations this week, while Luke Scrase won a pass to the end in the 'White Room' challenge that controversially saw Conor McIntyre leave the house with £50,000 - half of the prize fund - last Friday (August 3).
Luke A is currently favourite to win Big Brother with odds of 5/4, followed by Deana at 7/4 and Adam at 7/2.
Big Brother's next live eviction show airs at 9pm on Channel 5.
