Women in Black: Stars Attend Premiere of Former Beatles' New Video [SLIDESHOW]

A number of stars were in attendance at the premiere of former Beatle Paul McCartney's new video, "My Valentine". Interestingly, all those who came to the event were dressed in black!

The high-profile event saw Hollywood actresses like Gwyneth Paltrow, Jane Fonda, Kristen Stewart, Pamela Anderson and Julie Delpy, as well as supermodel Miranda Kerr and musicians Joan Jett and Gwen Stefani.

According to the Daily Mail, Kerr was stunning in a Stella McCartney design which had a wide split up the front with mesh panels down the left hand side. Meanwhile, Stefani was a little more daring, with sheer panels around a bustier and see-through portions down the side with a peplum top and trouser suit. Reese Witherspoon, who is pregnant, was also in attendance, with a black shift dress sporting cut-out detail on the arms and skirt.

The star couple of the day, though - McCartney and his wife Nancy - chose simplicity above all else. McCartney wore denims, a shirt and a navy blue jacket.

The event saw three music videos - shot for his new single - featuring actors Johnny Depp and Natalie Portman. Apparently it was Stella McCartney's idea and father Paul decided to direct.

According to the Telegraph, the video features Portman performing sign language to the song's lyrics and Depp playing a soulful guitar solo. The video, reportedly simple and sparse, is on 35mm film in black and white, and was shot by Oscar-winning cinematographer Wally Pfister.

McCartney said he was glad to have Depp and Portman perform for his video.

"Well they're just nice people, some friends from way back, and they were just very kind to do it, I was very pleased to work with them," he explained. "My Valentine" and "Only Our Hearts" are original compositions from the singer's fifteenth studio album - "Kisses on the Bottom."

"We thought thirty was like really old. Now I think it's amazingly young. There was a guy at John's art college who was 24 and we felt very sorry for him, he looked like a real old guy, he had a five -o-clock shadow, he looked really pathetic to us because we were like, 16 ... I'm really just some kid from Liverpool still," the former Beatle said, in a report by the Huffington Post, while promoting his video.
