He finished by discrediting the so called source who the alleged claims came from. "None of our friends would speak a word to bottom feeders," he insisted.
Quality Street heiress Millie and Stephen tied the knot during a romantic Somerset ceremony in September.
The couple were last spotted enjoying a night out together at the Groucho Club in London on 19 January. And just a few days ago Millie uploaded a picture of her husband accompanied by three hearts.
She followed this up with a picture of Stephen stood in the empty space where they are constructing their new home.
