Lopez hired a £20 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.
