Celebrities All Somehow Related Through Hollywood Hook-Ups

Every celebrity in Hollywood can be linked using a chart of their past hook-ups and relationships -- even Paris Hilton and Frank Sinatra.

That’s the idea behind Irad Eyal’s book, Sex Degrees Of Separation (Chronicle Books) and sexdegrees.net, which visually charts the busy love lives of the stars.

Eyal says you can connect just about anyone in Tinseltown because older serial daters like Jack Nicholson and George Clooney usually date younger women and “bridge the gap” between generations.

Therefore, even someone like Paris Hilton can wind up linked to Frank Sinatra.

Eyal says connections also stem from continuous partner- swapping. For instance, Terri Hatcher and Nicollette Sheridan both dated David Spade and Michael Bolton, while Owen Wilson and Lance Armstrong have traded Cheryl Crow and Kate Hudson.

But those who’ve really been around the block include Warren Beatty, Mick Jagger, Madonna, and Jennifer Love Hewitt.

Unfortunately, Eyal says the original degrees of separation game icon, Kevin Bacon, has only had two serious Hollywood relationships.
