"Huh?" she commented on an Instagram post that shared the news.
During Thursday's December 19 episode of "Watch What Happens Live", where she appeared alongside former One Direction star Liam Payne, a caller asked the star how she reacted to Lohan's apparent shade - something that didn't seem to faze the actress at all.
"It was very interesting. They announced that I was playing Ariel at the Hollywood Bowl and I think she wrote, like, 'What?' or something," she remembered. "I find it to be an honour, truly."
Lea added, "It's classic, classic. Because obviously, it's at the Hollywood Bowl, but it was great. I'm down with it, of course."
