Patrick Schwarzenegger attends senior prom with daughter of famous music producer

Over the weekend Patrick Schwarzenegger experienced a typical teen rite of passage—attending his senior prom—but it wasn't your average affair. That's because the 18-year-old son of Arnold Schwarzenegger and Maria Shriver attended the event with another celebrity offspring—legendary music producer Jimmy Iovine's daughter Jade.

Patrick—who, in addition to being a student, is a model, aspiring actor and a designer for the charity-driven clothing line Project 360—shared his prom photo with his more than 50,000 Twitter followers. In the pic, his classmate Jade, wearing a white, strapless dress, pins a boutonnière to his tuxedo. He captioned the photo: "Prom with my best friend @jadeiovine."

While Patrick doesn't go into further detail about their relationship status other than his "best friend" comment," Jade appears to be tight with the entire Schwarzenegger/Shriver family. In January it was announced that she was organizing the Young Woman's Conference at Brentwood School, which she attends with Patrick, and the honorary chair was Maria Shriver. She later wrote about the event for Huffington Post and talked about how she was bullied growing up. Jade is also friends with Patrick's sister Katherine Schwarzenegger and messages her on Twitter.

Jade is the youngest child of music exec Iovine, who has worked with everyone from John Lennon to Stevie Nicks. He's currently the chairman of Interscope Geffen A&M Records, but also serves as the mentor for contestants on American Idol. He had four children with his ex-wife Vicki Iovine, author of "Girlfriends' Guide to Pregnancy," to whom he was married for 20 years. Jade is their youngest child.

No word on Jade's college plans for fall, but Patrick was tweeting about his own after he was recently accepted by the University of Southern California. "I'm not going, but still I'm f-cking happy!" he wrote. He also applied to Georgetown, Stanford and University of Pennsylvania.
