Emily Blunt isn't "the overachiever" in her family.

The British actress has seen her Hollywood profile rise thanks to her roles in The Devil Wears Prada and The Young Victoria.

Emily - who is currently promoting The Five-Year Engagement alongside Jason Segel - has siblings Felicity, Sebastian and Susannah and marvels at how different their lives are.

"I always find it interesting how different siblings can be. I am not the overachiever in my family. My oldest sister is a literary agent - she's crazy smart and really cool," she told the British edition of OK! magazine.

"My brother is eccentric and funny. My little sister couldn't care less about this industry. She wants to be a vet."

Emily loves her career. The 29-year-old star admits it does have its downsides though.

"You have to love this job. It does knock you around at times. It's rewarding when you achieve something; when you get rejected, it does hurt," she said.

"I've been really lucky."
