Hollywood actress Gwyneth and her ex-husband, Coldplay frontman Chris Martin, were one of the first celebrity couple's to choose very unusual names for their children.
Chris and Gwyneth welcomed their first born child, daughter Apple Martin, in 2004, but it wasn't until 2012 that Gwyneth revealed the meaning behind the moniker.
"My husband named her!" she told Hello! Canada. "I thought it was so unique and sounded cool."
Their son Moses Martin arrived two years later in 2006.
His name is thought to be inspired by a Coldplay song called Moses, in which Chris croons about his love for Gwyneth.
Ashlee and Jessica Simpson
The Simpson sisters have been famous for many years, so it stands to reason they'd pick off-the-wall names for their little angels.
Ashlee is mum to son Bronx Mowgli Wentz and daughter Jagger Snow Ross, while Jessica has two daughters, Maxwell Drew and Birdie Mae, and a son Ace Knute Johnson with her sports star husband Eric Johnson.
Global superstar Beyoncé is a doting mum-of-three to daughter Blue Ivy and twins Rumi and Sir Carter with her husband Jay Z.
Blue's name is inspired by an essay by Rebecca Solnit which waxes lyrical about the significance of the colour blue in every element of the earth; her middle name, Ivy, represents the Roman numeral IV which has special meaning for Bey and Jay who were born on the fourth of September and December respectively.
The Carter's infant daughter Rumi is named after their favourite poet, a 13th century Persian author, while Sir is intended to symbolise their newborn son's masculinity.
In an interview with Rap Radar, Jay Z said of his son's name: "Sir was like, man - come out the gate. He carries himself like that. He just came out, like, Sir."
Bronx-born rap sensation Cardi B and her husband Offset welcomed their first child together last year, and gave the little girl a vey rare name: Kulture Kiari Cephus.
Cardi announced her daughter's name in a social media post, writing on Instagram: "Kulture! Anything else woulda been kinda basic okurrrrr!"
The tot's middle name, Kiari, is a nod to her famous dad whose real name is Kiara Kendrell Cephus.
