Madonna is in need of a ray of light. The pop superstar, 57, is “at her wit’s end” over her estrangement from son Rocco and her ongoing custody battle with her ex-husband Guy Ritchie, a source exclusively tells Us Weekly.

“She has been crying constantly over what’s going on with Rocco,” the insider tells Us.

As previously reported, the singer’s 15-year-old son declined to return to the U.S. for Christmas, instead spending the holidays with his father in London. Following Madonna’s plea, on December 23 a judge ordered the teen back to New York City, but an attorney for the British director argued that "Rocco has expressed very clearly" that he didn’t want to return to NYC.

“Rocco is a typical 15-year-old who wants to do what he wants,” the insider explains of the situation, maintaining that Madonna is a "fantastic mother" and that Ritchie has a hidden agenda.

“This entire thing is 40 percent Rocco and 60 percent Guy,” the source explains, adding that “Guy is trying hard to mess with her again” and is putting things in Rocco's head about his mother. He and Madonna divorced in 2008 after eight years together. 

Rocco, the source adds, also misses having big sister Lourdes around the house. “Rocco misses Lola so it’s really hard for him not having her around at Madonna’s house,” the insider explains of the siblings. “He is incredibly close to her so it’s really hard for him to be alone at his mom’s without her.”

"Madonna has been actively doing all she can to get her son Rocco Ritchie home and back to school in New York," another source previously told Us. “Rocco, along with Madonna’s other three children, have never been away from her for any extended period of time until daughter Lourdes went away to college last year," the insider added, explaining that Rocco’s absence will cause him to miss school in NYC.

"Madonna, who lost her own mother at a very young age, has always made her children’s education a priority along with their well-being," the source said.

Madonna is also mom of 19-year-old daughter Lourdes Leon, 10-year-old son David Banda and 9-year-old daughter Mercy. Ritchie has three young children with current wife Jacqui Ainsley.  

Us Weekly reached out to Rocco’s attorney for comment. Ritchie’s rep declined to comment.
