Cressida Bonas still has an in with the Royal family...with Prince Harry's cousins Princesses Beatrice and Eugenie! The trio took the town at Annabel's in London where Bonas rocked a Stella McCartney gown.

According to Mail Online they were all in bright spirits and partied in the exclusive club until 3 a.m. They were joined by David Clark, Princess Beatrice's long-time boyfriend.

Bonas complimented her look with lose blonde tresses simple makeup. She sure knows how to show her former flame what he is missing!

Beatrice looked equally as stunning as the model, donning a blue skirt with a white blouse and gold necklace.

Princess Eugenie introduced the stunning blonde to Prince Harry before they dated for two years. They split about one month ago allegedly after arguments over Harry's friend Guy Pelly's wedding.

Bonas was seen last week looking pale and thin after news emerged her ex was "twerking" with girls at the "unbelievably wild" party. She was offered "compassionate leave" from her marketing job while she copes with the difficult heartbreak.

It was also reported Prince Harry "hooked up" with a wealthy Tennessee socialite during his visit.

"The girl comes from a wealthy family in Tennessee," an insider revealed.

"There was lots of drinking. She stayed overnight. She's been bragging about it to friends," they added. "But to Harry it was just a hookup."

The aspiring actress seems to be adopting Kate, Duchess of Cambridge's strategy for winning Prince William back in March 2007. The former Middleton joined forces with sister Pippa and took the town by storm. William spent the summer working and enjoying himself as well, and they reunited in June.

However it does not seem that a reconciliation is likely, according to a source close to the Royal family.

"She is a lovely girl, and a beautiful girl, but this has run its course," they told People. "It wasn't to be."
