Kristen Stewart enjoys late night London party without Robert Pattinson

Robert Pattinson was spotted partying last week with friends; this week it was his girlfriend Kristen Stewart’s turn to let her hair down.

The Twilight star attended the wrap party for Snow White and the Huntsman, held at Loft Studios in London.

Kristen danced the night away with cast and crew, including co-stars Chris Hemsworth, Sam Claflin, and Johnny Harris, before reportedly leaving the club at 3.15am.

Johnny Tweeted: “Great #SWATH party tonight! Seen this crew work hard these last few months so it's lovely to see them celebrate and in party mode tonight! X”

Kristen appeared to be having a ball but sadly, boyfriend Robert Pattinson was nowhere to be seen. Who wants take their other half to a work do anyway?

Let’s hope Rob doesn’t have the same worries as Kris…

Kristen is said to be concerned when her boy hits the town without her, not because she doesn’t trust him, she just doesn’t trust the young ladies who hound the heartthrob wherever he goes.

A source told US Weekly: "It’s really difficult. Rob rarely goes out, but when he does, Kristen is wary, not because she doesn’t trust him, but because she doesn’t trust the girls."

Robert Pattinson Disturbed by Kristen Stewart in 'Breaking Dawn'

Robert Pattinson has admitted that Kristen Stewart looked disturbing in Breaking Dawn Part 1 when she was pregnant and giving birth. If you saw the film, you know that Bella Swan loses a ton of weight, and looks very pale and sickly when she is having Renesmee. You may have even thought it was hard to watch—and Rob understands why!

"It's definitely very strange considering we did most of the movie where she gets looking progressively worse and worse. It was actually quite moving to see her look as haggard and destroyed as she did. It's incredibly disturbing, even on the set," Pattinson said.

Kristen Stewart did look awful and whoever did her make-up did an amazing job at making her look... well, dead. It was freaky to watch and even though Rob knew it was "fake," he too was disturbed by the scenes. Luckily for him, he knew that Bella becomes a beautiful vampire in Part 2, and the gross scenes were probably all worth it!
