Presley, 38, and Lockwood exchanged vows in a traditional Japanese ceremony on Jan. 22, spokesman Paul Bloch said.
It was Presley's fourth marriage. She was previously married to Nicolas Cage, Michael Jackson and Danny Keough, who is the father of her two children.
The bride's mother, actress Priscilla Presley, walked her daughter down the aisle and gave her away, Bloch said.
Daughter Riley Keough was maid of honor and son Benjamin Keough was a groomsman.
The best man was Presley's first husband Danny Keough.
Also attending the wedding were Lockwood's parents, Vivian and William Lockwood.
Lockwood was Presley's musical director and is listed as executive producer on her 2005 album "Now What."
Presley lives in the Los Angeles area but Bloch said he didn't know where the couple planned to live.
