A “stalker” has admitted breaking into Madonna’s Marylebone house to steal a can of Red Bull a year after gaining access to another one of her homes in Wiltshire.

Grzegorz Matlok, who is being held in a secure psychiatric unit, admitted a single count of burgling an office linked to the Like A Virgin singer’s luxury home when he appeared at Southwark Crown Court on Monday (September 12).

It has been reported that the 30-year-old had previously entered one of her other properties and put on clothing belonging to her former husband Guy Ritchie. He was arrested for the offence but not charged.

One March 12 this year Matlok is thought to have used a rope to climb up to a balcony in the singer’s Marylebone house in the early hours of the morning.

He then roamed into a neighbouring house, also owned by Madonna, and then into an office used by the singer’s staff where he grabbed the soft drink.

A member of Madonna’s staff then apprehended the intruder and handed him over to police.

Although Matlok had originally claimed he brought the energy drink with him, his defence counsel Stephen Earnshaw said: “Mr Matlok accepts that it could not have been his can and that in using it and drinking it he has done something he should not have done.”

Matlok, of no fixed address, was remanded in custody ahead of his sentencing on October 10.

Madonna, 53, was not in the building at the time, having taken her children to America to pay her respects to her late grandmother.
