Katy Perry, who just unveiled her new single "Walking On Air," is spending some time in Europe. She attended the Chanel Spring/Summer show at Paris Fashion Week on Monday wearing a black and white floral gown.

The annual event draws dozens of celebrities and supermodels. Model Miranda Kerr turned heads in a pair of dresses with plunging necklines. On Sunday, she wore a tight, low-cut navy blue dress while shopping at the Stella McCartney store. She also participated in McCartney's spring-summer 2014 fashion show.

Kerr posted on Tuesday: "Grand Palais Paris! About to walk for Chanel" followed by "See you on the runway! #chanel #paris #fun."

Kim Kardashian and Kanye West left baby North at home for the Givenchy Womenswear show on Sunday night.  The reality star's custom-made dress was reportedly made in 24 hours prior to the fashion show.
