People have been left mind-blown after discovering this Hollywood icon's true identity. Actress and film producer Reese Witherspoons is one of the world's biggest stars, featuring in a slew of iconic titles including Legally Blonde, Cruel Intentions, Friends, and Sweet Home Alabama. But, the 48-year-old, from Louisiana, US, grew up with a totally different name - and only adopted 'Reese' (her mother's maiden name) as her professional moniker when she got into acting.

In a recent interview with Vanity Fair, with Big Little Lies co-star Nicole Kidman, the award-winning star revealed how the name still causes confusion when she's behind the camera. The pair discuss Reese's habit of calling fellow cast member Laura Dern by her second name, to which Nicole says: "I hate how you call her Dern. It sounds weird .

" But Reese explains the rationale behind the habit, stating: "I'm gonna tell you why...

Because my name is Laura, and her name is Laura, and it's confusing to me. My real name is Laura Jeanne."
