Millie Bobby Brown is celebrating a social media milestone.

"11 MILLIEon," the 13-year-old actress and "Stranger Things" star captioned last week's photo of her laying on the floor and covering her eyes with her hands while surrounded by boxes of roses that spell out "MBB11."

Brown put her influence to good use Sunday, urging her fans to treat one another with care and respect in the new year.

"Dear 2018; you're going to be jam packed with exciting events, projects, and new places! I know 2017 is going to be hard to beat but I say we make it an amazing year. Listen 2018, I know we're pals so do me a favor and tell everyone I need them to be kind and if you were kind this year i need you to be even kinder the next," she wrote.

"Happy new year."

The Spanish-born, British-raised star plays the super-powered heroine Eleven on Netflix's popular sci-fi series "Stranger Things."

Last year, she became the youngest actress ever to earn an Emmy nomination for Best Supporting Actress in a Drama for her performance.
