Pippa Middleton may be single again.

The famous sister of Kate Middleton was dubbed “Her Royal Hotness” after her stunning good looks wowed onlookers when she served as a bridesmaid at her sister’s wedding in April.

The British tabloids are all buzzing about the reported break-up with ex-cricketer Alex Loudon. Various publications have said Middleton, 27, and her apparently erstwhile boyfriend had been arguing in recent weeks.

According to a report in The Sun, an unnamed source said Middleton tried to get over the split with Loudon, 31, by spending the weekend with her sister and brother-in-law, Prince William.

“She and Alex split briefly in the summer — but this time it’s over. They are barely speaking,” The Sun quoted the same source as saying.
