Cara Delevingne’s 21st birthday is on the horizon, and she’s reportedly getting ready to party in Ibiza with some of her closest friends – including Joan Collins.

The glamourous 80 year-old actress and author may seem an unlikely guest, but she is in fact Cara’s godmother and a close family friend of the Delevingne's. And Joan still knows how to have good time as she was recently pictured with infamous party-girl Tracey Emin on a girly holiday.

Of course, Joan won’t be the only celebrity to attend Cara’s big birthday bash. Other guests set to attend include her good pal and roomie Georgia May Jagger, fellow partner-in-crime Rihanna as well as One Direction’s Harry Styles and Justin Bieber.
