Madonna has wished her ‘beloved’ son Rocco a happy birthday.

THE 59-YEAR-OLD singer has her eldest son with her former husband Guy Ritchie and took to Instagram last Saturday to ring in his 18th birthday with a series of adorable pictures.

On one picture of herself and Rocco when he was a baby, she wrote: “I am to My Beloved............#rocco#birthday #18 (sic)”

And then on another with Rocco when he was slightly older, she continued: “As My Beloved is to Me..........#rocco #birthday #18 (sic)”

Rocco’s birthday comes just one week before the Material Girl hitmaker – who also has Lourdes, 21, David, 12, Mercy James, also 12, and twins Stella and Esther, five – is due to celebrate her 60th birthday on August 16.

It was recently revealed the star is planning a special birthday bash at her Quinta do Relogio estate in Lisbon, Portugal – where she lives with her youngest four children – and is thought to be inviting Rocco as well as his father.

An insider said: “There are going to be quite a few celebrations for Madonna’s 60th, but she has said she wants to be surrounded by her family.”

Madonna moved to Portugal to help her son David achieve his dream of becoming a soccer star after he was snapped up for the Benfica junior squad.

She said recently: “I’ve been desperate to get him into the best academies with the best coaches, but the level of football in America is much lower than the rest of the world. I saw his frustration, and I also felt it was a good time.”
