Paris and Nicky Hilton spent the afternoon shopping on Robertson Blvd. in Hollywood yesterday, and Paris looked summery in a colorful striped dress and headband. Do you like her look?

The socialite's summer started off a little rocky after she lost her cellphone earlier this month. She tweeted, "I lost my phone last night, so if you texted me last night or today and I didn't answer, it's cause I didn't get it."

That tweet sent shockwaves through Hollywood - someone stole her T-Mobile Sidekick account back in February, 2005 and caused chaos in celebrity circles by gaining access to the numbers and details of the rich and famous.
