Kim Kardashian West has a pair of adorable workout buddies!

The mom of four, 40, shared a trio of photos on Instagram Wednesday from a sweet moment when her sons — 5½-year-old Saint and 2-year-old Psalm — came to see her when she was exercising. Psalm sat on Mom's lap and Saint came toting a tablet, both hugging and kissing Kim in the adorable mother-son session.

"Little visitors in the gym today," she captioned the post.

Kim shares four children with estranged husband Kanye West: daughters North, 8, and Chicago, 3, plus sons Saint and Psalm.

The reality star and the rapper, 44, began dating in 2012 and later wed in 2014. Following a challenging period in their relationship last year, Kim filed for divorce from the rapper in February after six years of marriage.
