Taylor Swift and Karlie Kloss have been seen on the streets of New York City together quite frequently as of late.

The country singer is now taking her new BFF's lead and going brunette, according to Life And Style magazine.

The "Red" hitmaker and her 21-year-old model buddy, who have been spotted leaving the gym together on multiple occasions, look even more similar now that she's changed her hair color, especially because both ladies rock a tall, svelte physique.

Despite the fact that they're growing to look increasingly similar, Karlie Kloss revealed that she and Taylor Swift are very different when it comes to their post-workout routine.

The "Dear John" singer reportedly takes an hour after working out to make herself look picture perfect upon leaving the gym, while Kloss doesn't even bring a gym bag to workout.

"I usually just grab my vinyl coin purse and go. . . I like to head home if I can to shower and get ready for the day," stated Kloss.

The supermodel recently revealed her workout routine and tips to Style.com just in time for bikini season.

"I like to exercise and get moving first thing in the morning. It's so important to change up your workout routine, so I like to take a range of classes," explained the new face of Nike, who reportedly does everything from SoulCycle, Pilates and ballet, according to Us Magazine.

Karlie Kloss is known for her killer abs. The model revealed that it doesn't take much to get her abs toned and flawless.

Kloss focuses on doing "good-old fashion sit-ups - it's something you don't need any equipment or trainer for and you can do anytime."
