The video documents Horner test-driving the Gorgeous Suite, one of the Scarlet Lady ship’s most glamorous cabins, as a favour to her longtime friend, Branson.
The vid shows her full RockStar experience, as she’s seen spinning records, reading Branson’s book, rocking out with a guitar, indulging in champagne and partying the night away in true Rebellious Luxe fashion.
Horner said: “Virgin Voyages’ RockStar Suites are the perfect blend of luxury, glamour and a little bit of rock and roll opulence – exactly the way I like to enjoy my holidays.
“After thorough testing, I think it’s safe to say these suites are rockstar-worthy and ready for Scarlet Lady’s debut next year.
“Everyone deserves to feel like a rockstar at some point in their lives… You’re in for a real treat.”
Branson added: “RockStar Suites celebrate Virgin’s musical heritage and how I got my start in the music industry.
"Geri and the Spice Girls were a wonderful part of that so I can’t imagine anyone better suited to give our RockStar Suites a whirl. Geri certainly looked like she had a great time.
“I’m very excited for our sailors on Scarlet Lady to feel like rockstars too.”
