Shenae Grimes formed unlikely friendships while shooting Sugar in the streets of L.A. earlier this year.
"I played a homeless kid and we had all real homeless kids as our background," Grimes, 21, said on Chelsea Lately Thursday. "I ended up just meeting the coolest people that I've met in L.A. on Venice Boardwalk."
The Scream 4 star added that she even helps her poverty-stricken pals beg for money on the streets.
"I feel bad, but I'm a cute girl, so I'm a really good sidekick for 'spanging' -- that's what asking for spare change -- and I don't need it myself, so I feel like I'm pulling one over on society," Grimes giggled. "It all goes to them, but I help out where I can."
Still, the Canadian actress admits she's had to set a few ground rules with her homeless friends.
"It's hard. You have to have boundaries. I've definitely been asked if they can sleep on my floor and stuff like that. You walk a fine line," she told host Chelsea Handler, 36. "My mom would not be pleased if I started taking homeless people to my apartment."
Still, Grimes doesn't regret befriending the film's extras. "It's just about reaching out," the 90210 actress explained. "As humankind, it's our responsibility to help take care of each other.
