Justin celebrated his wife by writing, "mother’s day sucks ass," on Instagram. Hailey then returned the favor by writing, “father’s day sucks ass” on one of his (dozens of) Father’s Day posts.

The Grammy-winning singer, who shares 9-month-old son Jack with Hailey, went viral last month for writing via Instagram that “Mother’s Day sucks ass.”

In a now-deleted reply to his post, Hailey answered with a direct remark that mirrored the one the “Peaches” singer had written for her on Mother’s Day. Justin Bieber’s inaugural Father’s Day as a dad to son Jack Blues was an interesting one.
