Eva Mendes once had a farting competition with Cameron Diaz

Hollywood screen siren Eva Mendes has revealed she once had a farting competition with Cameron Diaz.

The 'Stuck on You' star, 33, traveled to Nepal with the 'Shrek' star for an MTV show and confessed they stayed up in their hotel room breaking wind all night.

She said:  "Cameron is a big old belcher, but I can't belch. One night I had a heavy dinner, so I combated her belching with something I could do.

The actress - who began her career as a background beauty in Will Smith's 'Miami' music video, and shot to fame in the major Hollywood film '2 Fast 2 Furious', also revealed Will didn't remember where he had first met her when they starred together in 'Hitch'.

Eva, 33, added to Maxim magazine: "I expected Will to be like, 'Congrats, you've done well since your video girl days', but he didn't remember me. I said 'You don't remember me, do you?' and I saw a bit of panic in his eyes."
