Karlie Kloss Gushes Over the Backstreet Boys!

Karlie Kloss is pretty in black lace while attending the 2015 Pencils Of Promise Gala held at Cipriani Wall Street on Wednesday night (October 21) in New York City.

The 23-year-old supermodel was joined by actor Chiwetel Ejiofor and singers Usher and John Legend.

“Being tweeted at by @backstreetboys #lifegoals,” Karlie recently tweeted about seeing them perform at a Balmain party earlier in the week.
