PARIS, March 13 (UPI) -- Shia LaBeouf and Mia Goth sparked engagement rumors this week.
Goth was spotted with a large diamond on her left ring finger as she left Los Angeles airport Monday, and wore the ring at the Miu Miu runway show for Paris Fashion Week on Wednesday. The 21-year-old model was seen with the jewelry again as she arrived back at LAX on Thursday.
LaBeouf and Goth met on the set of Lars von Trier film Nymphomaniac in 2012, and were linked as a couple shortly after. A source told People the pair "seem very happy and spend a lot of time together," and said they "are usually just laughing and seem to have a great time."
LaBeouf previously dated stylist Karolyn Pho and actresses Megan Fox and Carey Mulligan. The actor last appeared with Brad Pitt in WWII film Fury, and is scheduled for post-apocalyptic thriller Man Down with Kate Mara in 2015.
