Feeling the heat: Cameron Diaz was seen carrying two bottles of water - along with a couple of pens, an iPad and two folders - on set in London today
It was one the hottest day of the year so far, with temperatures in the capital reaching a scorching 24C - and Cameron Diaz was taking no chances as she filmed her latest movie in London today.
The Green Hornet star was seen wandering around on location clutching two bottles of water, as well as an iPad, two pens and a ring binder.
However, despite the heat, the 38-year-old actress kept her now bulging muscles covered in a white jacket and a tight white T-shirt with skintight jeans and brown leather strappy sandals.
On set: The actress is starring in a remake of the Michael Caine and Shirley McLaine 1966 movie Gambit
She's filming crime caper Gambit here in which she stars with Oscar-winning The King's Speech star Colin Firth, along with Alan Rickman and Tom Courteney.
It's a remake of the 1966 Michael Caine and Shirley McLaine 1966 movie of the same name, which was nominated for three Oscars.
Shooting will begin in May in London on the film, with The Last Station's Michael Hoffman directing from a script written by Joel and Ethan Coen.
It tells the tale of a man called Harry Deane, played by Firth, who plans on stealing a painting from one of the world's richest men.
Fitness fans: Cameron and her baseball playing boyfriend Alex Rodriguez, seen here in New York earlier this month, are rumoured to be on the verge of getting engaged
The couple have been dating for almost a year and In Touch magazine claimed that Alex was spotted looking at rings in New York.
A source told the magazine: 'Alex is very loving toward Cameron and protective of her.'
In Touch claims that Alex was seen looking at a nine-carat diamond at the city's I. Friedman & Son Jewellers last month.
