Little black dresses are very much in vogue at the moment and not many look as good in one as Megan Fox.

The Transformers star looked drop-dead gorgeous in a sultry, sleeveless number combined with a lace neckline. Her dress complimented the actress's slim figure and also had a lace hemline.

She was continuing the hottest trend this winter of elegant black dresses that have been recently sported by Kylie Minogue, Alexa Chung and Kelly Brooke, to name just a few.

Megan, who was voted FHM's sexiest woman in 2008 and was runner up in 2009 and 2010, brought some added glamour to the phone launch she attended in Moscow.

She joined a number of Hollywood A-listers that were in the Russian capital to support the launch of the Vertu Constellation Quest at the Volkhonka Art Centre. The new phone is retailed at a hefty £17,000 and will be launched in more than 15 outlets in Moscow.
