Lots of ladies stopping by the Sirius studios for some on-air promotion.
Diane Kruger did hers in Vanessa Bruno dress, casual pony, and white flats.
Um, Piper kind of looks like a bad post-botox here, but I love her red Moschino bow neck dress! She wore gold Alexandre Birman closed toe pumps. This dress is sold out, too! No luck today!
Rose Byrne in Boy by Band of Outsiders at the studio...
...and with loose waves and a Rebecca Taylor jumpsuit for an appearance on Jimmy Fallon.
