Amanda Seyfried attended the screening of her new film "Lovelace" at the Mayfair Hotel in London, England, on Monday. The actress wore a sheer blue Gucci dress with Givenchy heels and completed her look with bright red lipstick.

Seyfried has been making quite a style statement while promoting her latest film. She wore a gold beaded halter dress that revealed a little sideboob at the Los Angeles premiere last week. In Las Vegas, Seyfried and her co-star Sharon Stone made a stunning pair in their monochromatic ensembles.

The biopic centers on Lovelace's transformation from the daughter of religious parents to an international adult film star.

A judge recently ruled that "Lovelace" can be released despite a legal challenge from the producers behind X-rated film "Deep Throat." Arrow Productions claimed they never approved the use of the porn clips in the biopic and demanded at least $10 million in compensation.

The film is currently in theaters.
