LOS ANGELES-Johnny Depp and Amber Heard have apparently confirmed they are set to wed by throwing a star-studded engagement party.

The Hollywood couple - who have been dating since 2012 - invited around 100 friends and family to celebrate with them at 1920s-themed Carondelet House in downtown Los Angeles, according to reports.

Celebrities including Marilyn Manson, Jerry Bruckheimer and Steven Tyler were on the guest list, and Johnny's children Lily-Rose and Jack, from his relationship with his ex Vanessa Paradis, also attended.

Partygoers were seen holding black invitations that said "A&J" on the front.

Amber, 27, wore a cream silk camisole and dark skirt while Pirates Of The Caribbean star Johnny, 50, donned a black suit and hat.

Guests were treated to food, drinks and a night of oldies rock songs including Wild Thing by The Troggs and Elvis Presley's Jailhouse Rock.

Johnny and Amber met on the set of their 2011 film The Rum Diary and started dating the following year.

While they have not confirmed they are engaged, it's thought Johnny popped the question on Christmas Eve and Amber has frequently been snapped flashing an impressive diamond ring on her finger.
