Jennifer Garner: Disney CinemaCon Presentation!

Jennifer Garner looks lovely on the red carpet at the Walt Disney Studio Motion Pictures CinemaCon 2012 event held at Caesars Palace on Tuesday (April 24) in Las Vegas.

The actress, who celebrated her 40th birthday last week, wore a Dolce&Gabbana dress, Nicholas Kirkwood shoes, and David Webb jewelry.

Jennifer attended the event to promote her upcoming film The Odd Life of Timothy Green, which will hit theaters on August 15.

The flick is about a childless couple (Garner and Joel Edgerton) who bury a box in their backyard, containing all of their wishes for an infant. Soon, a child is born, though Timothy Green is not all that he appears.
