Amber Heard has sparked speculation her wedding to Johnny Depp is just weeks away.

The 'Rum Diary' actress enjoyed a glitzy girls' night out - rumoured to have been her bachelorette party - with a small group of friends in New York City on Saturday night (12.04.14).

A source told the New York Post's Page Six that the 27-year-old actress and four friends went to see 'Queen of the Night' at Simon Hammerstein's Diamond Horseshoe at the Paramount Hotel.

The insider said the girls, who were dressed ''to the nines,'' dined on lobster, drank wine, and had ''the best view in the house of a sexy Chinese pole act.''

Another source told E! News: ''They looked like they had a good time and participated in the show just like everyone else.''

It was recently claimed Johnny, 50, and Amber are planning on having an intimate wedding on the Hollywood star's private beach in the Bahamas.

A source said: ''They're having a small intimate ceremony barefoot on the beach in Little Hall's Pond Cay.

''Afterwards they'll have a barbecue where some of Johnny's musician pals are going to perform, followed by limbo dancing.

''Neither Johnny nor Amber want a big, glitzy Hollywood bash. They are both very private.''

The 'Transcendence' star is letting his fiancée plan their big day.

He previously said: ''I think that I would be better at making women's shoes than I would be at wedding planning, I can't plan anything. I'm really bad at that stuff.''
