As the face of Lancôme, Emma was front and centre at the beauty brand's cocktail party at the Savoy.
Yesterday she launched Lancôme's new Valentine's range for lips and nails, and was obviously in the mood for love that evening with her red-themed outfit and make-up.

The actress looked stunning in a Valentino red lace mini and Louboutin heels, with her hair slicked back. We particularly adore the bow detail at the hip.
She wore a strong red lipstick from her collection named Rouge In Love, which she launched along with a nail polish collection called Vernis In Love at Selfridges in London yesterday.
Emma wore a black mini dress for the launch, which again had a cute bow detail.
She tweeted: "On my way to the launch of Lancôme Rouge in Love at Selfridges. Exciting! Em xx"
Harry Potter actress Emma became the face of Lancôme last March and designed the lipstick range.
She said: "It was probably the product I was most excited about when I came aboard Lancôme. I actually chose the color that I wore in shoot, which is a really bright red."
Caroline Flack and Fresh Meat's Zawe Ashton were also at the bash last night, and both went for black dresses with warmth a priority.
The cocktail party was held by BAFTAs' official beauty partner two nights before the big ceremony.
