Guests at the Caribbean wedding included Bruce's ex-wife Demi Moore and her husband Ashton Kutcher.
The Live Free Or Die Hard actor, 54, and his 30-year-old British model love began dating last year after meeting through friends. Bruce's publicist tells E! News the couple will have a civil ceremony when they return to California.
Bruce and Demi were married for 13 years before splitting in 2000. Their three daughters, Rumer, 20, 17-year-old Scout, and Tallulah, 15, attended the wedding.
