The X Factor contestant and the human rights barrister were both pupils at Dr Challoner's High School for girls in Little Chalfont, Buckinghamshire.
Honey G, whose real name is Anna Georgette Gilford, was three years below George Clooney's wife so their paths may very well have crossed.

The 35-year-old rap artist was even captain of the school's first tennis team from 1997 to 1999, The Mirror reports.
Dr Challoner's Grammar School is dubbed a "posh girls' school" whose values are to "educate, enrich and enable" according to their official website. The school became co-educational in 1906 and in the sixties, a new institution was built in Little Chalfont to house the girls, where Amal and Honey G went on to study.
While both the lawyer and the singer lead their lives in the spotlight, they couldn't be in more different worlds.

Amal, who was known by her maiden name Alamuddin at school, is a top barrister at Doughty Street Chambers and specialises in human rights. She was propelled into the public eye after marrying Hollywood actor George in 2014.
Honey G's time in the limelight has been more limited. She found fame a couple of months ago as a contestant on The X Factor. From her first audition, the budding artist made an impression on judges Simon Cowell, Louis Walsh, Nicole Scherzinger and her mentor Sharon Osbourne.
While some viewers have branded her this year's "joke act", Honey G has won over thousands of fans, including some very famous names.
Rapper 50 Cent has called her "entertaining" and admitted that he would like to "see her go far", while Robbie Williams told reporters at a London press conference on Monday: "I like Honey G. I think she is entertaining, much to everybody's dismay!"
