Emma Watson Declares Her Love for Steve Carell in Handwritten Note

A handwritten thank you note can go a long way.

Emma Watson proved this when she took the time to write Steve Carell a sweet message to thank him for his fashion choices at the Oscars. It turns out the 52-year-old Foxcatcher actor was wearing #HeForShe cufflinks, designed to support Watson's gender equality United Nations campaign.

The 24-year-old Harry Potter actress took to both her Twitter and Facebook to personally thank the Oscar-nominated comedian.

"You were pure genius in Little Miss Sunshine (one of my all time favorite films), my brother became obsessed with you after Anchorman, I wanted to marry you or have you adopt me after Crazy, Stupid, Love, I hated that guy you played in The Way Way Back, and then you were mind-blowing in Foxcatcher," she gushed. What about The Office, Emma?!

"I think you're so awesome and today you are wearing #HeForShe Monique Péan cufflinks at the Oscars to support Gender Equality," she continued. "Couldn't be more proud! THANK YOU."

But Carell wasn't the only actor supporting Watson on Sunday night. She also thanked American Sniper and Greek star Jake McDorman for also sporting the cufflinks, calling out his "Will act for food" quote on Twitter.

"Dear Jake, I wrote 'Will act for food' on the back of my graduation cap at Brown. We are clearly kindred spirits!!" she joked.

Watson, who was appointed to the role of the UN Women Goodwill Ambassador last year, delivered a speech on the floor of the UN to launch the new HeForShe initiative last September, which advocates for total equality without the use of negative rhetoric and also asks men to join the political and social battle.
