The former cricketer was nowhere to be seen, however, as Pippa enjoyed a city break in romantic Madrid with former flame George Percy earlier this month. And the 27-year-old's latest outing, to the French Open in Paris, was also sans beau.

She was accompanied by a dashing male friend, with whom she chatted and laughed throughout the match.
Opting for a casual look at the famous tournament, Pippa wore a fitted black T-shirt and polka dot ruffle skirt with a high grey waistband, later covering up with a white trench coat.
She teamed the ensemble with LK Bennett peeptoe wedges - the white version of the black shoes her sister has made famous – and a tan leather handbag.
