And we have a feeling the handsome Prince, 31, probably enjoyed meeting them too... We wouldn't blame him, they looked amazing!
The 'Black Magic' stars met William's younger brother at the Royal Albert Hall in London's Kensington on Friday night (13 November), the first time he had attended the event which his granny - the Queen - is the patron of.
Before meeting Harry, Perrie admitted she had a "crush" on him and admitted she was nervous about meeting him.
However, dressed in a stunning bejewelled gold dress, Perrie showed no sign of nerves when the exciting moment finally arrived.
Her three favourite girlies - Jade Thirlwall, Jesy Nelson and Leigh-Anne Pinnock also dazzled in a rainbow of sequins, feathers, jewels and glitter - GORGEOUS!
Bearded Harry, looking dapper in a traditional black and white tuxedo, also met the other performers on the star-studded night, including Elton John, Alesha Dixon, Ricky Martin, Kylie Minogue and One Direction.
In fact, Harry reportedly asked Harry Styles when he last had a hair cut!
Britain's Got Talent winner Jules O'Dwyer and her dog Matisse performed after winning the opportunity on the ITV talent show.
Comedian Jack Whitehall, who hosted the event, cheekily joked that Harry was "the King of banter" and said it would be great if he were in charge of the country for a week.
