Jennifer Lopez has hired a $30 million yacht for the Cannes Film Festival.

The 'Back Up Plan' star – who has two-year-old twins Max and Emme with husband Marc Anthony – is determined to ensure she has as much privacy as possible while she attends the famous annual French event and has acquired the vessel from fashion designer Roberto Cavalli.

A source told the Daily Star newspaper: 'The yacht comes with its own crew of four – so it's much plusher than any hotel.

'And Jennifer can have all her entourage under one roof.

'She was adamant she wanted a really private trip because she's got the babies with her so she jumped at the chance of staying on Roberto's yacht.'

Although Jennifer is doing her best to keep her family out of the spotlight, she and Marc have attended a number of high-profile events since arriving in France, including the Monaco Grand Prix and a Gucci party in honour of director Martin Scorsese.

Last year, Mariah Carey hired the luxury craft while she attended the festival to promote her movie 'Precious: Based On The Novel 'Precious' By Sapphire'.

However, the generous star – who is married to rapper-and-presenter Nick Cannon – also splashed out for her entourage to attend the prestigious movie event.

A source said at the time: "Mariah's really close with her team and couldn't bear the thought of a couple of people not being able to come, so she paid for it out of her pocket. That's virtually unheard of in the celebrity world."

David and Victoria Beckham have also previously hired the yacht.
