Brad Pitt saves time by freshening up with baby wipes rather than showering.

The 45-year-old actor - who raises six children with partner Angelina Jolie - is often so busy caring for his family he doesn't have time to wash.

Brad's "Inglourious Basterds" co-star Eli Roth revealed: "He shared that when you're sweating and don't have time to take a shower, you just take a baby wipe and rub it under your armpits.

"He said to be on set, 'I've got six kids. All you've got to do is just grab them and have a couple of quick wipes under the pits. Man, I'm getting peed on all day. I don't have time to take a shower.' "

Brad shared his time-saving tip with Eli when they were filming a scene together for the new movie, during which Brad was shocked to discover his co-star hadn't had time to bathe.

Eli, 37, explained to People magazine: "Brad said, 'Damn, you're ripe.' I said, 'I didn't have time to shower.' He said, 'Baby wipes, man, baby wipes.'

"I thought that was the greatest tip. My character is called the Bear Jew. If I ever started to smell like a bear, I would just use a couple baby wipes under the armpits, and it made it safe for everyone else to act around me."

Eli loved working with Brad, who he believes is the "biggest movie star in the world".

He explained: "He taught me a lot of acting tricks. We all wanted to ask him about his old movies like 'Fight Club' and 'True Romance', and he was so cool to talk about all that stuff with us. Right from the first day, we were all a little shy. But then somebody asked him about '12 Monkeys' and he talked about everything."
