Nicolas Cage Aggressively Sings Purple Rain While His 4-Day Marriage Ends

National Treasure 3 looks crazy. In this chapter, Nicolas Cage plays himself getting divorced just after four days of marriage to Erika Koike in Vegas. Deep in LA's Koreatown, We find Nic and his vocal cords assaulting the Prince classic, 'Purple Rain'. Clearly his emotions have gotten the best of him for this karaoke rendition. Definitely an appropriate song choice for his current situation but I don't see any musicals in his future. In all seriousness, this divorce definitely is taking a toll on him considering Koike is seeking "spousal support." Check the tweet below for the video and full info via TMZ.
