Madonna insists she is a 'good mother' despite being on the road for work.

The 57-year-old mother-of-four is currently performing shows as part of her Rebel Heart Tour and she doesn't believe travelling frequently has a negative impact on her parenting skills.

"Its (sic) possible to be an entertainer and a good mother!!!" she wrote on her Instagram account Saturday (9Jan16) in a caption attached to a picture of herself spending family time backstage with her four kids - Lourdes, 19, Rocco, 15, David, 10, and Mercy, nine.

Madonna closed out the post lamenting about how she thinks women who raise children on their own are viewed as a whole, with the star writing: "Too bad we don't live in a society where many encourage strong independent single working moms! The next great Frontier! #revolutionoflove continues #rebelheart4ever".

Madonna shares her thoughts amid a fresh custody battle she is having with ex-husband Guy Ritchie over their son Rocco.
The teenager reportedly refused to spend Christmas in New York City, where he lives with his mother, instead choosing to stay in the U.K. with his father. Although Rocco has expressed interest in living with dad Guy in the U.K. permanently, a family court judge declared he must first go back to New York before a decision on future custody could be hashed out between his parents.

Madonna and Guy divorced in 2008 after almost eight years of marriage. Guy recently remarried, tying the knot with Jacqui in July 2015 - he shares three young children with his new wife.
