Mandy Moore, Ciara, Rachel Bilson Say Stop Texting!

Stars hit a party to encourage people to stop driving while distracted

Celebs like Ciara, Rachel Bilson and Mandy Moore want us to stop being textually active...at least when we're behind the wheel.

They were just a few of the stars at Nobu West Hollywood last night for Elle magazine and Express' Hit the Road, TXT L8R campaign party, hosted by Ciara (who admitted her new short 'do is actually a wig.)

Rachel came without her engagement ring, but newlywed Mandy Moore told us the person she texts most is her hubby, Ryan Adams.

Twilight's Nikki Reed and Kellan Lutz were also on hand. So what did they have to say about Rachelle Lefevre's recasting?

Nada. They refused to do any interviews at the party.

Also making a quick appearance at the bash? Paris and Nicky Hilton. The sisters posed for pics before heading to In-N-Out to get some food.

Also hangin' at Nobu? A pregnant Camila Alves and 90210 castmates AnnaLynne McCord and Jessica Lowndes.
