The estranged couple - who split in 2013 following three years of marriage - have allegedly been meeting up with one another whenever they get the opportunity and believe the close relationship they share is beneficial for their son Flynn, four.

A source told the US' OK! Magazine: "[They have been] enjoying hooking up whenever the mood and opportunity strike. They also claim that this arrangement is good for their son!"

The 31-year-old model and the hunky actor, 38, have remained on good terms since their split but sparked rumours they may be taking little steps to try and rekindle their romance last month when they left the Vanity Fair's Oscars after-party together.

Speaking about her former lover last year, Miranda had nothing but nice things to say about him, gushing: "we both love and care about each other and genuinely want each other to be happy... we do everything to make sure our relationship is harmonious."

Since their shocking split, the Australian beauty - who began dating the English star in 2007 - has been romantically linked to billionaire businessman James Packer and pop star Justin Bieber.

Orlando was rumoured to be dating the 'Baby' hitmaker's on/off girlfriend Selena Gomez, 22, last year but he soon poured cold water over the speculation when speaking to TMZ.com.
