Givaudan perfumer Mary Pierre Julien has worked with Kate Walsh, Grey's Anatomy actress, in creating both Boyfriend and Billionaire Boyfriend fragrances.

For the first fragrance, Boyfriend, Walsh wanted to capture a boyfriend's scent that lingers on. New fragrance, Billionaire Boyfriend puts the focus on a rich boyfriend, Walsh told WWD, “This is a story of fun, indulgence and decadence. The sky’s the limit,”

Her thoughts on the new fragrance?  "Nobody wants to buy a fragrance called Husband. I think the idea of Boyfriend connotes fun, a kind of frivolity and romance. Anything can happen as opposed to with a husband or a fiancé, where things get serious and heavy and possibly end in lawsuits,” she said, adding, “It was really about a nod to these guys. Now, we don’t have to necessarily get married, [but I felt like saying,] ‘Hey fellas, we really like you, and we love romance. We like the simple things like wearing your shirt or your jeans.’ These are the kind of romantic, sensual things that I wanted to give a shout out to.”
