Red haired actresses Amy Adams and Isla Fisher may look alike to some people but they are definitely not the same person.

Isla, who is best-known for credits such as Wedding Crashers and Confessions of a Shopaholic, appeared on Jimmy Kimmel Live recently to promote her new book Marge in Charge.

The actress talked about Lady Gaga seeing her at the Vanity Fair Oscar party one year and praising her for her performance in American Hustle. She also did an amusing PSA explaining the differences between her and Amy Adams, and Jessica Chastain.
