The 24-year-old star was recently enjoying dinner out at a restaurant in West Hollywood when the cast of the hit US show approached her.
According to TMZ, the cast walked up to the star and apologised to her for mocking the amount of times she's been to rehab in an episode of the show that aired last year.
They told her that they didn't mean to hurt her feelings and Lohan accepted their apology before they left her to enjoy her dinner.
It is claimed cast members Lea Michele and Jane Lynch were not present during the meeting.
