yes it seems to be true, I found an extract of the script on the web:
"Lana! I won't laugh! Come on, please?" Chloe heard Clark say as she walked towards the Torch office one morning.
"Hey guys, what's going on?" Chloe asked as she took in Clark standing in front of Lana and Lana standing with her arms firmly across her chest and her jaw clenched so tight that Chloe could see her jawline from the doorway.
"Today's Lana's big day, remember?" Clark said, looking at Chloe, then turning back to face Chloe.
"Oh! I forgot! Let me see, Lana!" Chloe grinned widly as she entered the office and dropped her bookbag in the chair in front of her computer, then joined Clark standing across from Lana.
"No." Lana said simply.
"Why not?" Chloe questioned.
"She's thinks I'm going to laugh at her." Clark sighed.
"I know he won't! I got them to!" Chloe said in Clark's defence.
"You won't laugh either?" Lana asked Chloe.
"Never." Chloe said, flashing Lana a huge grin.
"Ok, but don't tell Whitney...he hasn't seen me yet." Lana sighed, letting her arms fall to her sides and looked straight at Clark and Chloe, smiling broadly The morning sun streaming in through the windows glinted brightly off her...braces.
