Kate Middleton's younger sister, Pippa, wonders why guys are running away! After attending her seventh wedding of the year earlier this month, a friend of the 28-year-old tells Life & Style that Pippa has begun to wonder whether she'll ever be the one standing at the altar. "Pippa is scared she'll never find someone who'll be able to accept her life," the friend tells Life & Style.

In November, after growing increasingly uncomfortable with her fame, longtime boyfriend Alex Loudon called it quits with Pippa for the second time this year. Ever since the split, according to the friend, Pippa has been deeply worried that she's become undateble, now that she's the sister-in-law of the future king of England.

"The men Pippa knows are all majorly turned off by the circus surrounding her," an insider reveals. Things have gotten so bad, one British magazine has even dubbed it the "Pippa Problem."

"Pippa is happy for Kate and for her old university friends who are getting hitched, but she's starting to wonder if she'll ever find her own Prince Charming," the friend tells Life & Style.
