David 'The Hoff' Hasselhoff and his girlfriend Hayley, TV presenter Amanda Lamb and her husband Sean, and singer Brian McFadden and his wife Vogue Williams are the celebs taking part tonight.
As they're asked a series of questions about their partners, the couple who know the most about each other will go through to play for the charity jackpot of £30,000.
All the couples take home £5,000 for charity and a Mr & Mrs carriage clock for their mantelpiece. Who will prove they're soulmates?
All Star Mr & Mrs, ITV, 8pm
