On the day, all eyes on the day were on Pippa’s dazzling dress, but as the ceremony came to a close, rumour has it the younger Middleton sister stepped out on the arm of her royal wedding date, Alex Loudon.
It’s thought the Eton-educated 30-year-old accompanied Pippa, 27, on the day, but kept a low profile, waiting in the wings while his wedding day date fulfilled her royal duties.
'Alex thinks it's hilarious that suddenly the world has discovered Pippa,' one insider reportedly revealed of the ex-professional cricket player, who now works in business.
The rumoured pair are said to be smitten with each other, but were determined to keep a low profile ahead of the William and Kate’s nuptials.
'He's madly in love with her,' the source added. 'Of course he was never going to do anything about it while she was helping Kate arrange her wedding.'
Pippa caused a stir by waltzing her way down the aisle in a slinky winter white Alexander McQueen gown. But we couldn’t shake the feeling we’d seen it before. And we had! On Cameron Diaz, at Golden Globes in 2009.
