Rylan Clark-Neal has revealed he and Viscountess Emma Weymouth have history together - as he previously performed at her wedding.
The presenter, 30, was interviewing Weymouth on Tuesday's Strictly Come Dancing: It Takes Two when the pair made the admission.
Joking about her title, Clark-Neal asked: “Before we go any further, milady may I call you Emma?"
Weymouth, 33, responded "please do" and the presenter then told viewers that he needed to be "upfront and honest" about something.
He said: “We have crossed paths before, and where was that?”, to which the dancer responded: “At my wedding.”
Professional dancer Aljaz Skorjanec – who is paired with Weymouth in the competition – gasped in shock as photograph of Clark-Neal and the Weymouth was shown.
The former X Factor star added: “I performed a Spice Girls megamix at your wedding! It's when my teeth were just put in. It’s so lovely to see you again."
Weymouth - formerly known as Emma McQuiston - announced her engagement to Ceawlin Thynn, Viscount Weymouth, in 2012.
The couple later tied the knot at their family estate, Longleat House, on 8 June 2013.
The Viscountess is the first member of the aristocracy to take part in Strictly.
She and Skorjanec danced the Cha Cha to She’s A Lady by Tom Jones in the first live show of the series, receiving a total score of 19 from the judging panel.
They will face the public vote in Saturday night’s episode, before one couple leaves the show in Sunday's results show.
Strictly Come Dancing continues on September 28 on BBC One.
