London, May 11 (IANS) Actress Eva Mendes says posing in her underwear gives her the motivation to stay slim because she knows she must resists junk food to stay in great shape.
The 37-year-old star often has to strip off for sexy photo shoots and hence staying fit is always on her top agenda, reports femalefirst.co.uk.
"My job requires me to do a lot of underwear and bikini shoots. That's what encourages me to put the chocolate-chip cookies down," she said.
Although she is very conscious of eating healthily, but she admits, she wasn't always like this.
"I never cared about exercise or what I was eating until I got into my 20's and then I started to really get into it. I just wasn't feeling good, so I started eating well, working out and going from drinking no water ever to up to three litres a day," she said.
