Who's Nicole's Ex Dating?

Nicole Richie and Brody JennerNow, we all know that the love lives of the stars can get quite complicated.

So, we'll try to explain this little knot of exes and new unions very simply.

You may remember that Nicole Richie and Adam 'DJ AM' Goldstein broke of their engagement in August 2006.

Now she's dating Brody Jenner, the star of a short-lived US show called Princess Of Malibu.

Well, it turns out that Brody's ex - Laguna Beach girl Kristin Cavallari - could be dating Nicole's ex, DJ AM.

Got it?

Nicole, 24, and Brody, 23, are childhood pals and they started dating three month's after she and DJ AM split.

Brody split with his on/off ex, Kristin, in July.

Adam 'DJ AM' Goldstein and Kristin CavallariAdam, 33, (that's DJ AM in case you've got a bit lost) was spotted out with Kristin, 19, recently at a New York party.

However, his rep told the New York Daily News: "AM is dating, but not Kristin Cavallari. They are just friends."

They tangled webs these celebs weave, eh?
