Fans in Australia have recently seen Bianca agree to marry Liam Murphy (Axle Whitehead), but it appears that bad boy Heath (Dan Ewing) is still on her mind as she slips up on her hen night.
Making a speech in front of her friends, Bianca makes a blunder as she names Heath as her future husband - causing raised eyebrows as some Summer Bay residents don't believe she is over him.
Lisa Gormley, who plays Bianca, told TV Week: "There's a speech and Bianca accidentally toasts the wrong man and says Heath's name. Bianca thinks it's the most hilarious thing in the world, but other people around her think it's a bit more serious."
Fortunately for Bianca, an oblivious Liam later agrees that they should not tell each other what went on at their respective hen and stag celebrations.
Gormley added: "[Liam is] the best thing in the world and she'd never want him to find out.
"Bianca had a few champers and, to her, her slip-up doesn't mean anything."
Home and Away airs these scenes next week on Network Seven in Australia and in late February on Channel 5 in the UK.
