The movie star gathered his two kids, Lily-Rose and John Christopher, his sisters, and his mother Betty Sue Palmer's closest friends, including a housekeeper and her manicurist and took them out for dinner at Ago Restaurant in West Hollywood, according to TMZ.

The party saluted Palmer, who passed away three days before Depp's now-estranged wife Amber Heard filed for divorce to end the couple's 15-month marriage.

Johnny has only recently returned to Los Angeles for the first time since his divorce drama unfolded last month (May16) - he retreated to his private Bahamas island upon his return from Europe, where he was touring with his rock band The Hollywood Vampires.

The band, also featuring Alice Cooper and Aerosmith guitarist Joe Perry, will hit the road again for dates in the U.S. on Friday (01Jul16).

Meanwhile, he'll face off with his wife for the first time since they split and she requested and won a temporary protection order against him in a Los Angeles courtroom in mid-August (16), when Heard's request for a permanent restraining order against Depp will be discussed.

The couple was scheduled to face off in court earlier this month (17Jun15) but the hearing was postponed amid reports Depp and Heard were attempting to reach a private settlement.

The actress has accused the Pirates of the Caribbean star of abuse throughout their relationship and showed up at court last month with a bruised face, accusing Johnny of throwing an iPhone at her. In response to Heard's abuse allegations, Depp's lawyers have claimed the actress is "attempting to secure a premature financial resolution by alleging abuse".
