Lorde on Twitter

Lorde on Twitter (May 18, 2014)

International pop star Lorde was busy performing at the Preakness this weekend, but before she did she squeezed in a late night nail treatment — thanks to an unsuspecting Baltimore salon owner.

"The mgr of the nail salon I just visited stayed open until 10:30 p.m. on a Friday night for me (and not because of da famez, she had no idea)" she said on her Twitter account @lordemusic Friday.

The 17-year-old Grammy winner talked up Baltimore's City Nails and Spa to her 1.61 million Twitter followers this weekend. Not a bad advertisement for the small salon that opened in April.

"I didn't know who she was. She act like a normal person," owner Kay Parkchareonpaisan said Monday. Parkchareonpaisan said Lorde seemed like just another customer other than the fact she brought a few people with her.

"Is that your boyfriend?" Parkchareonpaisan asked about the man with Lorde. But when Lorde replied that was the man was her security guard, Parkchareonpaisan knew she had more than just a regular customer.

"She said she was singing at Preakness, but I didn't know how big she was," Parkchareonpaisan said. "My husband and I had to Google her when I got home."

She later posted a photo and plugged the salon at 1128 Light St. in Federal Hill.

"I got such great service. They're a new business so give them a helping hand if you need a nail spa in Baltimore," the "Royals" singer tweeted.

"She was just so nice. You would never know she was famous," Parkchareonpaisan said.
