The did the perfunctory bit on Tuesday by all accounts, ahead of their bells and whistles extravaganza in the Bahamas this weekend.
The Mortdecai star, who got engaged to the 28-year-old actress in December 2013 after meeting on the set of The Rum Diary, reportedly legally tied the knot with her at their home in Los Angeles two days ago.
A source told PEOPLE.com that they exchanged vows during an intimate civil ceremony ahead of their bigger wedding on the 51-year-old actor's private island, Little Hall's Pond Cay.
The tight-lipped insider managed to share: "They're great together."
Another source recently revealed Johnny, who has two young teenagers with ex-partner Vanessa Paradis, was rather looking forward to make Amber his missus.
The source said: "He's completely in love and can't wait!"
The couple are believed to have chosen to wed this month in order to fit in with their hectic work schedules.
A friend previously explained: "She's filming a movie in London, and he's getting ready to film the next Pirates of the Caribbean (the franchise that just keeps giving) in Australia. So this is the only time that everyone could get together."
The duo's relationship was rumoured to be on the rocks last year after that awards ceremony incident, but a pal recently insisted they are now in "a really good place."
Well, they'd want to be; marriage - although it has its upsides - has a certain hum of finality or "Oh, you again" about it. Just me? Just as well I love him to bits.
