Jennifer Lopez graces cover of Beauty book

Jennifer Lopez's face has been featured on the cover of a beauty book.

The stunning actress was snapped especially for make-up artist Scott Barnes'

new book About Face which is based on how to transform yourself and look like a film star.

Jennifer, 40, has worked with the beauty mogul for over 10 years and he even travelled with her when she worked on her latest movie, The Back-Up Plan.

His new book will be launched in two versions - one for the US and one for Britain. The US version contains the tag line "Amazing transformations using the secrets of the top celebrity make-up artist" on the cover.

Jennifer - who the make-up maestro has previously called his "muse" - has posed elegantly for the two front pages. The US version shows her sporting natural cosmetics with her hair tied up, while on the British pictures her with hair dramatically blowing away from her face.

Jennifer also wrote the foreword for the book.

Last night, Jennifer dressed up in a classic black strapless Louis Vuitton dress for the exclusive launch at Club Provocateur, inside New York's Hotel Gansevoort.

She looked stunning as she helped Scott promote his latest work.

The pair was joined by fashion designer Christian Siriano and former Destiny's Child singer Kelly Rowland.
