Washington: Robert Pattinson and on-off girlfriend Kristen Stewart were seen celebrating her birthday with 40 other pals at a margarita-fueled dinner at Malo, a Mexican eatery in Silver Lake, California.
An eyewitness said that the large group, which included `Spring Breakers` star Ashley Benson , partied with Mexican food, beers and margaritas, while the `Snow White and the Huntsmen` star seemed to be in a great mood, People magazine reported.
The onlooker claimed that the couple was a bit affectionate, but mostly mingled separately.
The group later headed to No Vacancy at Hotel Juniper in Hollywood for drinks.
A source told the publication that the 23-year-old actress smiled all night and the happy pair looked like they were back to normal.
