Fox reprised her role in the 2009 sequel, Transformers: Revenge of the Fallen.
Later in 2009, she starred as the eponymous lead in the black comedy horror film Jennifer's Body.
In January 2013, Fox was featured in a Brazilian television commercial for Brahma beer.
She told Esquire in January 2013 that her Christian faith is still very important to her; she believes it keeps her grounded.
Lynn Hirschbergnov of The New York Times opined that "the Jolie comparison would probably have been made by the media eventually, but Fox sped up the process" by "linking herself to Jolie" and that she created an "entertaining copy" by telling "tales of darkness and lust." It also positioned her as a potential role model, and later led to her being typecast.
