Mega-hottie Megan Fox doesn't need the ubiquitous 20-something's mini skirt to make an entrance: At the 2010 Teen Choice Awards, the new Mrs. Brian Austin Green donned très chic separates from French designer Isabel Marant.

Megan Fox may be best known for her uber-sultry role in Transformers but, at this awards show, she looked more the part of demure new wife in a blue-and-white printed cap-sleeve blouse and silver lamé pleated skirt. Megan finished the look with plum peep toe platform pumps.

Look for Megan onscreen next in Passion Play, opposite Mickey Rourke.
