Which Hilton Sister Will Tie the Knot First?

Celebutante sisters Paris and Nicky Hilton have never really been fans of the single life.  The long-legged beauties tend to change boyfriends more frequently than they change their outfits.

Recently though, something seems to have changed in their patterns of serial dating; both heiresses are happily in serious relationships and suddenly the altar is not seeming too far off.

Now the question is, which sister will be the first to take the plunge?

Nicky has been dating David Katzenberg for two years now, and Star Magazine is reporting that David bought a rock for his girl just last month.

Paris, on the other hand, has only been dating Good Charlotte’s Benji Madden for nine months, but has been opening up more than Nicky about plans to marry and start a family in the very near future.

Neither Hilton has a very good track record; with Nicky’s quickie Vegas wedding and annulment, and Paris’ short-lived engagement to Paris Latsis, it’s hard to imagine either of the sisters actually going through with it.

Only time will tell…
