Yesterday Katy Perry launched her custom brand of fake eyelashes, "Katy Perry Eyelashes by Eylure" at The Americana in Glendale, Calif.

The singer looked 1950s chic with a twist - her updo was her signature vibrant shade of blue to match her dress. The newly single pop star was all smiles at the event. She seems unaffected by rumors her estranged husband Russell Brand is dating a Mexican artist.

Perry's eyelashes are available at ULTA Beauty stores.
