Mario Testino and Emma Watson

Photographer Mario Testino is seen with Emma Watson on the set of a photoshoot for Lancôme in Paris yesterday (Mar. 16). The Harry Potter star has been in the French capital since Monday shooting a campaign for the high-end makeup brand.

Watson teased her fans over the weekend before announcing on Monday that she was the new face of Lancôme. She tweeted:

"A new venture is starting - what can it be? Follow my clues and you will see..."

"I'll pierce your skin if you hold me wrong but I'll love you forever if you pass me on."

"I'll be seen through a lens that has seen me before. Do you know who I mean, or do you still need more?"

"Are you keeping pace? No? Don't lose face, it's not a race. We share our birthplace..."

"It's a beauty house that wears a hat. French? Very, but this is no beret."

"This Pretty Woman was their latest recruit. Other great actresses have previously followed suit."

"It starts with an L and ends with an E. I’m sure you have guessed the new face of Lancôme is me!"

Emma Watson is looking beautiful as ever on the set of her photoshoot for her new employer Lancôme Tuesday in Paris (Mar. 15).

Emma should have plenty of time to be a good brand ambassador. She announced last week that she's leaving Brown University for a few semesters to focus on her professional career:

"As you know, I love Brown and I love studying pretty much more than anything but recently I've had so much to juggle that being a student AND fulfilling my other commitments has become a little impossible.

"I've decided to take a bit of time off to completely finish my work on Harry Potter (the last one comes out this summer) and to focus on my other professional and acting projects. I will still be working towards my degree... it’s just going to take me a semester or two longer than I thought : )

"Hope you are all well! Thank you for all your continuing support."

It was only announced yesterday that Emma's the newest face (aka "ambassadress") of Lancôme. The company's president Youcef Nabi said in a statement:

"Lancôme is pleased to announce the arrival of Emma Watson as new ambassadress of Lancôme. Thanks to her charm, romanticism and her incredible modernity, Emma Watson has become the icon of her generation. we are delighted by this new collaboration with Emma who brings a fresh spirit to Lancôme."

Emma's in great company - Anne Hathaway, Penelope Cruz, Julia Roberts, and Kate Winslet have all represented the French company in the past.
