Hailey Baldwin shows off her killer abs in a sports bra and matching leggings as the blonde beauty hit the gym in Beverly Hills the other day. The 23-year-old color coordinated her sexy ensemble with a pair of Adidas Nite Joggers by Beyonce.

Meanwhile, she and hubby Justin Bieber arrived and departed separately from their Wednesday night church service at Hillsong Wednesday night. Hailey is seen with a gal pal while Justin and pal Jaden Smith set out to grab dinner at Mastro's.
