"Don't Put All Your Eggs In One. basket," Madonna quipped in another post.
Meanwhile, Rocco's stepmother, Jacqui Ritchie, shared on Instagram that she and Guy were in the Maldives over the weekend, celebrating their sixth anniversary.
Madonna had reason to celebrate last week when a U.K. judge ruled that the custody dispute over Rocco's residency is to be decided in a New York court or through family mediation. "I renew, one final time, my plea for both parents to seek and to find an amicable resolution to the dispute between them," Justice MacDonald said, according to court docs obtained by ET. "Most importantly, as I observed during the course of the hearing, summer does not last forever. The boy very quickly becomes the man. It would be a very great tragedy for Rocco if any more of the previous and fast receding days of his childhood were to be taken up by this dispute."
The court also released Rocco's passport to him "for the purposes of travel at Easter."
Madonna has been battling her director ex regarding where their teen son should reside since this past December. Rocco is currently living in London with his father, while his mother is desperate for him to return to live with her in New York.
