Chris Martin and Gwyneth Paltrow aren’t the only Hollywood stars keeping company with Jay-Z. Natalie Portman is also a friend of Shawn Carter.

The rapper and Oscar nominee spent time together recently in Hollywood, catching a laser show. “I actually felt like I was in a time machine last week when I went with Jay-Z to the Laserium in Los Angeles,” she tells Interview magazine for the September 2009 issue. “But, dude, watching this display is like you’re in the ’70s. It was like a Zeppelin show. You could just see how these lasers were once the peak of technology and why everyone was so stoked about them.”

Portman also revealed that she has a guilty pleasure for “obscene hip-hop” and the Ying Yang Twins. “I love it so much. It makes me laugh and then it makes me want to dance,” she explains. “I’ve been listening a lot lately to ‘Wait (The Whisper Song)’ by the Ying Yang Twins, where the lyrics are like, ‘Wait ’til you see my dick’—which is just amazing because it’s whispered. [Whispers] ‘Wait ’til you see my dick…’ [Laughs] Crazy. So I just listen to it like I’m a five-year-old, like, ‘Oh my god! I can’t believe he just said that!'”
