What's going on with young Hollywood? Do they all date the same 12 people? And why are some of them getting engaged so quickly, when everyone knows that the relationship will probably end in a nasty breakup? The '80s Brat Pack has nothing on today's young hormone horde, whose love lives are starting to look like a game of musical beds, er... chairs.
After ending her brief engagement to Greek shipping heir Paris Latsis, Paris Hilton took up with another Greek shipping heir, Stavros Niarchos, shortly after Niarchos broke up with Mary-Kate Olsen. Meanwhile, Avril Lavigne is engaged to Hilton's ex-boyfriend, Sum 41 singer Deryck Whibley.
Lindsay Lohan was hot and heavy with Wilmer Valderrama for several months last year. After their breakup, he was romantically linked to Ashlee Simpson. Simpson's ex-boyfriend, Ryan Cabrera, was spotted canoodling with Kimberly Stewart in October, although Cabrera insisted to the press that he and Stewart were just friends. Stewart had apparently taken up with Cabrera after dumping her fiance, 'Girls Gone Wild' mogul Joe Francis, who also used to date Hilton.
Before breaking up with Francis, Stewart was engaged to musician Cisco Adler, who is now dating and rumored to be engaged to Mischa Barton. In November, Stewart went through another quickie engagement and breakup, this time with 'Laguna Beach' star Talan Torriero. (Stewart and Torriero got engaged after two months of dating. Their engagement lasted less than two weeks.)
After Britney Spears and Justin Timberlake broke up, she was briefly linked to Jared Leto and Colin Farrell. (Notorious playboy Farrell is also rumored to have had a fling with Hilton.) Then in 2004, Spears went through a quickie marriage and annulment to childhood friend Jason Alexander, before marrying Kevin Federline all within a matter of months.
Timberlake moved on to Cameron Diaz after she ended her relationship with Leto, who has more recently been linked to Scarlett Johansson, Lindsay Lohan and Ashley Olsen. Ashley dated Leto after breaking up with nightclub impresario Scott Sartiano. After Ashley, Sartiano then moved on to briefly dating Simpson. Leto's ex-girlfriend Johansson has more recently been dating Josh Hartnett, who was romantically linked to Katie Holmes earlier this year.
And Holmes, of course, has been involved in her own high-profile whirlwind engagement to you-know-who.
Got all that?!
