The pop star was spotted leaving a gym in LA wearing the lingerie brand's Strappy Plunge Sports Bra (£14.70 from victoriassecret.com).
Swift had a busy day going for an hour-long workout followed by a visit to buy arts and crafts supplies (possibly to make a get well soon card for boyfriend Calvin Harris).
The Victoria's Secret sports bra may be flying off the e-shelves already, but it's also available in VS stores and comes in a range of colours including lime green and hot pink.
Just trust us when we say, thanks to Swift, it won't be around for long.
