In this sneak peek of tonight's episode, husband-to-be Victor find out exactly what his partner Brendán has in store for him and to say he's not pleased would be an understatement.

Victor Garcia and Brendán O’Regan are the happy couple featured on this week's episode but whether or not they'll remain a happy couple by the end is in serious doubt.

Harry Potter superfan Brendán is the one in the driver's seat and Victor, who has never even seen the films, is left to deal with the shock of having a wedding day that includes dragons, cauldrons, owls and broomsticks and a nuptial outfit that's more Halloween than wedding dream.

'Don't Tell The Bride' airs tonight at 9.30pm on RTÉ2.
