Talk about getting your due.

UK-based fashion designer Rosie Huntington-Whiteley is paying tribute to her late friend and former co-star, Caroline Flack, who was "a true modern-day British beauty" -- and a "legend of a person," according to the fashion house's statement.

The pair starred on the TV show "The X Factor" in 2015 alongside Olly Murs, a musician friend of Huntington-Whiteley who recently tweeted that he's "all my friends" with "one extra person."

Snaps of them on set have circulated online, with one revealing a tuxedoed Flack smiling for the camera.

Huntington-Whiteley -- whose own modelling career has included Vogue cover articles and work for Versace, Louis Vuitton and Prada -- further paid tribute to Flack's "clever, sharp mind," referring to her 10 years as an employee at "The X Factor" and its spin-off, "The Xtra Factor."

"She was quite often the brains behind the production in those days, sending me quips, ideas and getting the shows together for us to go off on," she said.

"She will be forever remembered for her infectious smile, beautiful tan and showbiz charm. She had a way of making everybody feel so special, and was always there to offer a friendly ear."

Flack, a former host of "Top of the Pops," hosted a number of British television programs, including music show "The Xtra Factor," before appearing on ITV's "Love Island."

She left after the series' third series in July, citing "personal reasons" for her departure, in what some felt was a wobbly patch for the reality show, which has been surrounded by rumours of scheduling disputes, illness and bullying among the cast.
