Emma Watson looked red hot in Valentino as she attended a Lancome-hosted pre-BAFTA party at The Savoy Hotel on Friday in London.

The 21-year-old Harry Potter star recently uncovered a new campaign for Lancome lipstick called Rouge in Love.

Watson looked beautiful in a red lace and satin frock by Valentino, slicked back hair and black stilettos as she arrived for the party.

A large bow on the left side of her skirt, which elegantly sat on her hip as she posed for photos on the red carpet, added to her graceful costume.

She was also wearing a matching ruby red lipstick from her new collection “Rouge In Love”, which she launched at Selfridges in London along with a nail polish range called “Vernis In Love”.

Watson, who is a spokesperson for Lancome, attended the party which was held two days before the main event of which Lancome is the official beauty partner.
