Rosie Huntington-Whiteley attended the launch party for the new Samsung Galaxy Note II mobile phone in Beverly Hills, Calif., on Thursday.

Rosie showed off her model figure in a short and sheer black dress that showed off her legs. The bodice was sheer with just a few thin panels keeping her modesty in check.

The model-turned-actress recently designed a range of underwear for British department store Marks & Spencer. "I drew on my experiences as a model to create lingerie pieces that work on the body and are as comfortable to wear as they are beautiful," she explained over the summer.

Rosie starred in "Transformers: Dark of the Moon" and will appear in the upcoming film "Mad Max: Fury Road." She is currently dating action star Jason Statham.
