Madonna has spoken out in support of her son, Rocco Neil Hall/Reuters

Pop diva Madonna broke her silence over the arrest of her son Rocco Ritchie for possession of marijuana back. The singer released a statement and called her 16-year-old son's arrest a "family matter".

"I love my son very much. I will do whatever I can to give him the support that he needs, and I ask that you respect our privacy at this time," the singer said in a statement.

Rocco, who lives with his father Guy Ritchie, was arrested for possessing a small amount of cannabis in north-west London. The Scotland Yard said in an official statement, "The arrest follows a stop and search by officers from Camden borough on Wednesday, 28 September. [Rocco] was dealt with by way of Triage, which uses multiple strands to engage and educate young people in order to prevent re-offending."

Madonna was reportedly not pleased when her eldest son refused to return to the US to celebrate Christmas with her in 2015. She was involved in a year-long custody battle with her ex-husband and Rocco decided to stay with his father in the UK.

However, the mother-son duo resolved their differences after Madonna visited Rocco in London in September. "She's meeting with his school and watching over him to be the parent while his dad is away," a source told Us Weekly.

After returning to the States, the Express Yourself singer shared a throwback black-and-white photo with her son on Instagram. She captioned the image as "Still my Sweet Boy." Madonna and Guy tied the knot in 2000 and got divorced in 2008. They also have a 10-year-old adopted son David.
