Robert Pattinson and Kristen Stewart emerged from their 'paparazzi prison' to do a spot of clothes shopping in Vancouver last week.

While the Twilight co-stars – and rumoured couple – managed to dodge photographers, they didn't escape the notice of eagle-eyed fans as they trawled the rails at Retro Rock Vintage Clothing.

The pair even posed for pictures during their shopping trip, reports robsessedpattinson.com, who have photographic evidence of the thrift store visit.

Fellow vampire Kellan Lutz recently spoke out about the impact of the heartthrob's paparazzi following on the cast's daily routine.

Refering to the current Eclipse shoot, he said: "It's going great. We all love Vancouver. It's just that there's just so many paparazzi everywhere.

"We've been moving around to new places like every two weeks. Especially for Rob - we feel bad for him. Like, we go out to cast dinners and, whenever Rob's shooting, that's when we can have free time because usually that's when everyone is trying to shoot Rob or Kristen.

"So then we can actually be free to walk around the city and shop and go out to eat. You know, when we want to do cast dinners, it's tough because you can't just chill."

It's great to see that Rob and Kristen get to bust out of that prison once in a while!
