LOS ANGELES, June 6: In a recent exchange captured by Vanity Fair, Hollywood stars Reese Witherspoon and Nicole Kidman shared a lighthearted moment as they discussed an intriguing aspect of their friendship with fellow actress Laura Dern.

During the conversation, Kidman questioned Witherspoon's habit of referring to their "Big Little Lies" co-star Laura Dern by her last name, prompting a gentle clarification from Witherspoon.

"I hate how you call her Dern," Kidman confessed, prompting Witherspoon to explain, "'Cause my name is Laura, and her name's Laura, and it's confusing to me."

Witherspoon then reminded Kidman that her full birth name is Laura Jean Reese Witherspoon, with "Laura" being her first name. She adopted "Reese," her mother's maiden name when she embarked on her acting career.

While Kidman acknowledged forgetting that both her co-stars shared the same first name, she remained puzzled by Dern's choice not to address Witherspoon by her first name.

Witherspoon, however, light-heartedly shrugged off Kidman's confusion, remarking, "You're trying to understand something that just makes no sense."

The exchange shed light on Witherspoon's early start in the entertainment industry, beginning with a commercial at the age of 7 and later making her feature film debut in "The Man on the Moon" at age 14, a milestone she fondly reflects on as a pivotal moment in her career.

Reflecting on her journey in a 2021 Instagram post, Witherspoon expressed deep gratitude for the experiences that shaped her path to stardom.

The light-hearted banter between the two actresses offered fans a glimpse into their camaraderie behind the scenes, showcasing their playful rapport and mutual affection for their fellow cast members.
