Tell ya what, Lindsay is getting fierce mileage out of that Esurance ad...
The 28-year-old star poked fun at her Esurance Super Bowl commercial - in which she played a reckless driver and 'sorta mom' - by dressing up as Jimmy's sidekick Guillermo.
Lindsay donned a curly black wig and fake moustache and disguised a reportedly "pretty pink dress" in an oversized blazer complete with 'Jimmy Kimmel Live! Security' emblazoned on the pocket.
Speaking to the camera at the start of the show, Jimmy said: "But first, a message from our friends at Esurance ... You know, some companies base your insurance based on general categories such as your age and gender, not really based on you yourself. Isn't that right Guillermo?" There are a few titters, but then the real Guillermo steals the show by appearing as the "Sorta Lindsay Lohan".
Hilarity ensues.
Esurance's Super Bowl advertising campaign also saw Bryan Cranston reprise his role as crystal meth dealer Walter White pretending to be a pharmacy worker named Greg who tries to give a customer a dodgy prescription... treat yourself.
