Nothing like a new cell phone to bring out Hollywood's bold faced names for a big shindig in the name of new technology.

The Samsung Galaxy S3 has been touted as "the Android phone to take on the i-Phone," so of course Joe Manganiello, Anna Faris, Ashlee Simpson and Marisa Tomei came out to celebrate in a private residence in L.A.

Dave and Odette Annable, Aaron Paul, Anna Kendrick, Ashley Benson, Olivia Munn, Mark Salling and Billy Burke also swung by to test out the new phones and pose for pictures.

Magic Mike star Olivia Munn and Breaking Bad’s Aaron Paul checked out the Samsung Galaxy S III at the launch party.
