Pippa Middleton parties in Paris!

Pippa Middleton has been seen partying in Paris! The sexy sister of Kate Middleton — who has been in France watching the French Open with friends — was spotted dining with pals on rustic country food at Cinq-Mars on the Rue Verneuil, People magazine reports.

She then headed off to the St. Germain strip to party at Le Montana nightclub, which opens after midnight.

Recent reports claimed Pippa’s love life is on the rocks because of her jealous boyfriend. Sources said she riled stockbroker Alex Loudon by becoming an international sex symbol.

“They’ve been dating less than a year and already talking marriage — Alex actually proposed months ago. But Pippa told him they should hold off because an engagement would steal Kate’s limelight,” dished one insider.

“Alex agreed, but jealousy boiled right after the royal wedding when he and Pippa partied at the boozy, all-night postnup bash.

“Alex was furious because he felt Prince Harry overstepped his brother-in-law boundaries and flirted outrageously with Pippa.

“He confronted her about it the next day, but she just laughed it off. Now Alex is saying: ‘Enough is enough!’ He wants the world to know Pippa’s taken.”
