Pictures of Katy Perry and Kanye West at the Jean-Charles de Castelbajac Runway Show in Paris

Katy Perry and Kanye West greeted each other yesterday at the Jean-Charles de Castelbajac runway show during Paris Fashion Week. Katy donned an electric blue wig for the presentation, where she and Kanye shared a hug before taking their seats in the front row. Kanye also attended Givenchy on Sunday, where he and Liv Tyler wore matching outfits. Those are just some of the celebrities who have traveled to the City of Lights for the stylish festivities. Jennifer Hudson and Zoe Saldana toasted Michael Kors at a party there earlier this week, and Blake Lively's new position as a Chanel spokesmodel was celebrated at a private dinner on Saturday night. Russell Brand didn't join his wife for her trip, but the pair spent some time together in LA last week before she headed to Europe and she was on his mind when he hit the red carpet in NYC on Monday.
