Lindsay Lohan – who began shooting her spot on ABC's Ugly Betty on Saturday - continues to earn rave reviews from the show's cast and crew.

"She was terrific - a pleasure," Ugly Betty creator Silvio Horta tells Usmagazine.com. "She came in early and was very pleasant."

Lohan plays Kimberly, "a queen bee girl who Betty went to high school with," Horta says.

Lohan first appears on the May 22 season finale "in a flashback" dodge ball game, Horta says.

"Kimberly is doing the picking," Horta says, "and it doesn't turn out well for Betty."

(She's one of the last to be picked!)

Horta says Lohan will return for five episodes next season.

"They're going to run into each other," he says of the two characters. "Kimberly's life has taken a turn for the worst."
