During an interview, where Slash goes through each of his album tracks, he stated:
I got hip to Fergie being probably as good or better a rock singer than she is a pop singer. I heard her do Barracuda, the old Heart song, and I was like, fuckin’ wow!
I ended up doing a couple of shows with her where she sang Barracuda and Sweet Child O’ Mine. She’s one of the most phenomenal fucking rock ‘n’ roll singers, male or female, I’ve ever heard.'
Slash told The Sun: "The track began as a piece of music I'd written as a score for a strip bar scene and it made me think of [Fergie]. I'm a guy and there's nothing sexier than seeing a cute girl sing rock 'n' roll." 
On August 27, 2010, it was announced that Slash was filming a music video for the song. Slash stated that "[The] concept is twisted; Fergie's idea." The video for "Beautiful Dangerous" premiered on Vevo on October 26, 2010. The video first depicts Slash at a strip bar. Fergie - apparently, a stripper herself - seems to take an interest and flirts with him. After secretly dropping a drug into his drink, they leave the bar and head to a hotel. Slash, having been drugged, is held captive by Fergie and tied to a bed. Fergie mounts, kisses, and threatens him with a knife. In the end, she stabs Slash, killing him.
