Pharrell Williams joins actress Jessica Biel in a sultry new ad for Revoln's "Grow Luscious Plumping Mascara." “Pharrell is such a great person and I’m a huge fan of his music, so I was excited when he was chosen to participate, I think having someone like him incorporated into the commercial really makes it stand out,” Biel tells Elle Magazine. The commercial features beats and vocals from the N.E.R.D. founder as well the always-sexy Biel applying the finishing touches to her lashes while her suitor stumbles to approach her.
