Lisa dared to show her underwear

Luke, Rebecca, Mario and Lisa were in the luxury bedroom when Mario dared Lisa to walk through the house in just her underwear last night.

Looking at his girlfriend wearing just her pants and bra, Mario said it would be funny for her to shock the other housemates in her skimpy attire.

Bex, Luke and Mario gathered at the bedroom window as Lisa strode out in her polka dot underwear.

Mario noted that "conversations had stopped" between the other housemates, while Bex broke into giggles.

Returning to the luxury room, Lisa said the boys had called "air time" as she strode past them.

Meanwhile, Luke noted that Mohamed had almost fallen on the floor.
