Katy Perry got lucky in West Hollywood this week – but it’s not what you think.

The singer won a host of casino-themed games at an L.A. bash debuting her brand-new flavor of popchips. Kind of appropriate for a pop star, right?

Meanwhile, Selena Gomez celebrated her Nylon magazine cover with a little help from her friends.
