British actress Talulah Riley Monday filed divorce papers in Los Angeles Superior Court to end her marriage with tech billionaire Elon Musk.
Local media quoted a joint statement as saying that the divorce is amicable and the pair agreed that Riley would file the petition to end their latest marriage.
Musk and Riley have been separated for six months and say they will remain friends.
Musk, 44, filed for divorce in December 2014 but withdrew the petition seven months later.
Riley, 30, got married with Musk in 2010 and divorced in 2012. They re-married 18 months later but now separate again.
The couple do not have any children together, although he has five sons from a previous marriage.
Musk, who co-founded Paypal, founded and ran two leading tech companies -- e-car company Tesla Motors and SpaceX, which designs, manufactures and launches rockets and spacecraft.
