Upscale Hollywood flower shop House of Petals celebrated its one-year anniversary last Wednesday (9/4) with a party that included an appearance by none other than Eddie Van Halen. Ed—who is friends with owner Joey House, and who had appeared at another House of Petals event earlier this year—hung out at the party and strapped on his guitar for one song. Joining him at the shindig was his new girlfriend, Janie Liszewski.
