big Brother's wedding task will take a further twist tomorrow night when Mario and Lisa are asked if they want to marry for real, according to a report.

Show chiefs have told the couple that they must pretend they are not together if they want to win immunity from the first eviction. Instead, Mario is pretending that his girlfriend is fellow housemate Stephanie, who he proposed to as part of the challenge yesterday.

Once the truth is revealed tomorrow, Mario and Lisa will be given the opportunity to tie the knot in front of their fellow housemates, according to the Daily Star. The Big Brother house has been licensed for marriages and the minister recruited for tomorrow's fake wedding is able to conduct ceremonies for real.

"Having put Mario and Lisa through an emotional wringer, we're keen to reward them with a happy ending," an insider told the newspaper. "An on-air marriage would be a real coup for the show. We've got our fingers crossed we can pull this off."
