Chris Pratt is engaged to his girlfriend of seven months, Katherine Schwarzenegger.
While she has a very recognisable last name, the 29-year-old doesn’t share the same level of stratospheric fame as her Jurassic World-starring fiancé.
So, who is Katherine Schwarzenegger?
Well, as you might have guessed from her distinctive surname, she’s the daughter of action movie star Arnold Schwarzenegger and journalist Maria Shriver.
But while her father’s former role as the Governor of California gives her a strong link to politics, she is also a descendant of one of America’s best known political families, the Kennedys.
Maria's mother, Eunice Kennedy Shriver, was John F Kennedy, Robert F Kennedy and Ted Kennedy's sister - making the former US president and his politician brothers Katherine's great-uncles.
Despite connections to both politics and Hollywood (she and her younger siblings grew up in Los Angeles), Katherine has chosen to go down a career path that more closely resembles her mother's.
Like the 63-year-old, she's an author.
