Every time Prince Louis attends a public event, he is the talk of the town thanks to his hilarious and endearing demeanor.

However, according to body language expert Judy James, 5-year-old Prince Louis has stiff competition when it comes to being the cheekiest young royal. In fact, James now has his second cousin, Savannah Phillips, 12, occupying the throne.

"With royal rebels Zara and Mike (Tyndall) as aunts and uncles, stoic Princess Anne as grandmother, and younger royal children leading the fun circle, Savannah Phillips is currently the most rebellious young royal to win the title, exclusive but competitive No wonder she is leading the pack of runners," James told Express.

"Savannah's poise defines her as fearless and supremely fun. Not a mischievous rebel, but the most playful and often hilarious of the late queen's great-grandchildren."

From James' perspective, Savannah seems to possess many fine qualities - including her normal attitude toward her second cousin, Prince George, despite the somewhat intimidating fate that awaits him.

"When it comes to George, the future king, she is refreshingly irreverent," the expert observed. If she's not pulling faces and making him laugh, she's holding his mouth with her hand on the royal balcony or pushing him down the hill with her polo."

James also noted that Savannah seemed to have supported her father, Peter Phillips, admirably at the late queen's memorial service last year, showing that her playful side does not detract from her gentle nature.

Savannah is the eldest of the late queen's great-grandchildren, but technically, the queen's youngest grandchildren (Lady Louise, 19, and James, 15th Earl of Wessex) are closer in age to the next generation than their first cousins, so they are easily confused.
