Victoria Beckham has revealed the real reason behind her trademark pout - it covers up her insecurities.

The former Spice Girl has long been renowned for pursing her lips on the red carpet and is rarely seen with a smile on her face.But Beckham is adamant the reason she never looks happy is because she can't wait to leave the high-profile parties she so regularly attends and get home to her family with soccer star husband David.She tells America's Elle magazine, “People think I’m a moody b**ch. I do have my insecurities. Maybe that is why I look a little bit serious.The kind of person who’s going to stand on the red carpet and love the attention and have the big grin - I’m just not like that. I want to get in there, do what I’ve got to do, and get home to my kids.”
