Twilight stars Robert Pattinson and Kristen Stewart looked smitten during private party

Robert Pattinson and the rest of the Twilight crew got together on Saturday night to celebrate Kristen Stewart‘s 21st birthday.

The gang hosted a private party at Rockwell’s Bar & Grill in Vancouver during a break in filming.

Guests are said to have eaten oysters before tucking in to Kristen‘s chocolate birthday cake.

Rob led the crowd singing for her, and you could tell she was so embarrassed but in a cute way!’ says an onlooker.

‘Everyone was in a good mood, but it was a bittersweet night [as filming is almost complete].’

Kristen was presented with a motorcycle from her co-stars and she spent the evening thanking boyfriend Rob, 24, for the lavish gift. 

Rob and Kristen were together all night,’ the onlooker tells Us Weekly.

‘They held hands and he kissed her cheek a bunch of times.’
