Ashley Olsen, one of the twins from the former "Full House" TV sitcom, was out and about in Bluffton and on Hilton Head Island this week.
Market manager Kimber Viljac said she wondered if it really was Olsen when she noticed the actress, but some young people there confirmed it was.
Olsen obligingly posed for a photo to help promote the nonprofit market, Viljac said, then quickly moved on before other people spotted her.
Viljac said Olsen left with fresh local produce.
Olsen also stopped by The Cottage Cafè in Bluffton for lunch Thursday with two friends.
Sarah Ramirez, an employee there, thought she recognized the star, but wasn't sure until a co-worker slipped a note to Olsen, asking if she was the famous actress. Olsen responded by leaving an autograph.
Olsen ordered steak tacos at the restaurant, Ramirez said.
"She was just real chill," Ramirez said. "She just hung out and relaxed. She wasn't all snooty. ... She was just like a regular person really."
Olsen also was seen Wednesday and Thursday mixing drinks and wiping down tables with friends at Vine in Coligny Plaza on Hilton Head.
The restaurant's owners said Olsen was in town to visit their daughters, who are longtime friends of the actress. She headed back to Manhattan on Friday.
Olsen and her twin, Mary-Kate Olsen, starred on "Full House" from 1987 to 1995. Ashley is also a fashion designer, producer and author.
