Liv Tyler and Viggo Mortensen have topped a new list of Hollywood's highest-earning on-screen couples thanks to their Lord of the Rings romance.
The pair's Middle Earth lovers, Aragorn and Arwen, helped director Peter Jackson rake in $2.9 billion at the worldwide box office -- making them the top-earning Hollywood couple, according to a new Forbes magazine list of duos who have appeared in at least two films together in the last 20 years.
Tobey Maguire and Kirsten Dunst's onscreen chemistry in the Spider-Man franchise pulled in $2.5 billion, while Leonardo DiCaprio and Kate Winslet's doomed relationships in 1997's Titanic and Revolutionary Road in 2008 earned a combined $1.9 billion.
Meanwhile, Shia LaBeouf and Megan Fox's adventurous affair in the two Transformers blockbusters took in $1.5 billion.
But Forbes editors predict the fourth-place entry -- Twilight lovers Robert Pattinson and Kristen Stewart -- will have the most bite when the vampire franchise is completed.
Pattinson and Stewart's passionate relationship in the first two installments of the franchise has already grossed $1.1 billion -- and two Twilight follow-ups have yet to hit theaters.
George Clooney and Julia Roberts' flirtatious pairing in Ocean's Eleven and Twelve rounds out the top five couples with $847 million.
Sam Worthington's romance with Zoe Saldana in the world's highest-grossing film of all time, Avatar, was ineligible for the list because the duo has only starred in one film together.
