The 22-year-old model walked the runway at the brand's annual show at London's Earls Court Exhibition Centre while her 24-year-old pop star pal performed, with them even stepping down together at one point, and the blonde beauty thinks the 'Shake it Off' hitmaker should be an ''honorary'' face of the lingerie company.
Karlie told Britain's Grazia magazine: ''Taylor should be an Angel herself. She looks pretty heavenly out there. I'd say she's definitely an honorary one.''
This year's show was the first time it had been held in London and Karlie and her fellow Angels loved the sense of camaraderie on the trip.
She said: ''It's been like a sorority outing.''
Behati Prinsloo - who is married to Adam Levine - added: ''It felt like I was back in high school on a hockey trip, it's been such an amazing experience.''
Taylor performed two tracks at the show earlier this month.
During her second song 'Style', which she played during the Angel Ball section, Taylor strutted up the catwalk with her close friend Karlie.
The two blondes - who became pals after hanging out at last year's Victoria's Secret Fashion Show in New York - were wearing matching black lace underwear for the moment.
Taylor was styled in high-waisted black panties with a matching bra top and a lace long-sleeved top over it which had a long flowing train.
Karlie's raunchy ensemble was comprised of black stockings, suspenders, briefs, high heels, a see-through black lace bodysuit and a huge flowing midnight black cape.
Earlier in the show, Taylor performed her latest single 'Blank Space' during the Dream Girl segment for which she wore a powder pink satin slip teamed with a pink satin and black lace robe and fluffy pink peep toe heels.
The musician playfully gave high-fives to some of the Angels as they walked the catwalk and danced seductively during the fashion extravaganza.
From Halsey to Foo Fighters, these tracks tell a parent’s story with raw honesty.
