Elton John and David Furnish sell their high-rise Hollywood apartment over safety fears for their son Zachary ..

Upgrading: Elton and David are planning to raise a family in this Beverly Hills home which they bought recently

The source continued: 'Despite all the constant attention they give Zachary, Elton and David feared that the toddler could climb out of one of the apartment’s many windows and fall.

'Zachary is very precious to them, and Elton remembered what happened to his close friend Eric Clapton who lost his son Conor in such a tragic way.

'They thought about installing window guards all throughout but Elton was terrified that one of them could malfunction or break, and he couldn't live with that on his conscience.'

The 49-storey Sierra Towers is home to numerous Hollywood stars.

Cher and Joan Collins are current residents, and former Friends star Courteney Cox recently purchased a two-bedroom home in the block.

Former residents include David Geffen, Sidney Poitier and Lindsay Lohan
