Reps from both sides, however, insist that everything is fine.
“Lindsay was scheduled for six episodes and is appearing in four but had a lovely time,” a Lohan spokesperson said.
“America is grateful to have had her on the show and thinks everyone should tune in to see how great the episodes are,” Ferrera rep Carrie Byalick said.
Producers of the ABC series tell PEOPLE, “Lindsay wrapped up her arc and is done filming. She did a great job and we enjoyed having her. Viewers can look forward to her episodes tonight and next week.”
But on-set sources painted a much different picture for Page Six, citing spats, an out-of-control entourage, and one embarrassing moment.
According to a production source, Lohan and her people were so destructive that her dressing room had to be repainted. Lohan also refused to go on set before Ferrera did, according to the source.
Trouble erupted after one particular scene in which Ferrera’s character pulls down Lohan’s pants. A Lohan friend told Page Six Ferrera wasn’t supposed to pull down Lohan’s pants because it was a rehearsal. When she did, Lohan, who was only wearing a g-string, was embarrassed to the point of tears.
Lohan’s friend also said that the dressing room might have been wrecked by the cast of another show, and that the so-called entourage consisted of nothing more than Lohan’s manager, assistant, a sober companion and girlfriend Samantha Ronson.
“America was mean to Lindsay. Producers give her too much power,” Lohan’s pal says. “Lindsay didn’t do the last two episodes because America didn’t like her and got her kicked off.”
If true, the debacle provides a handy retort for the cast of Gossip Girls, which Ferrera recently slammed for conditioning people “to be mean.”
