While Madonna and ex-husband Guy Ritchie have not settled their months-long transatlantic custody dispute over teenage son Rocco, she hasn’t forgotten her son’s place in her heart, even if he isn’t living in her home.

The pop star, 57, rang in Easter with an Instagram photo early Sunday, showing decorated eggs with names for each of her kids – including Rocco.

“Easter = New Life,” she captioned the photo, along with a string of celebratory seasonal emoji.

(A second photo had a slightly more tongue-in-cheek caption: “Don’t Put All Your Eggs In One. basket.”)

Madonna’s legal fight with Ritchie, 47, began in December, when, a source told PEOPLE in January, Rocco left his mother to live with his father in the U.K., whose parenting style he preferred.

A source previously told PEOPLE that Ritchie “wants Rocco to have the confidence he lacked growing up and thinks Madonna’s stern parental style is counterproductive … The welfare of Rocco is Guy’s priority.”

But a source close to the singer, while alleging Rocco had missed some school, said in January, “Madonna is a devoted mother, and a big priority is her children’s education.”

Madonna has made frequent references to her relationship with her son, both on social media and while on tour.

“There’s no love stronger than a mother for her son, and if I talk about him too much, I’m going to cry,” she told a New Zealand crowd earlier this month.

While attorneys for all parties, including Rocco, are working toward a settlement, they will head back to New York court for a hearing on June 1, if no agreement is reached.
