Here’s yet another cross body purse sighting on Rachel Bilson. I have yet to make an official count but I think she’s the reigning cross body purse queen here on our blog!

The sighting was made on the the 28-year-old actress’s zoo trip to the LA Zoo & Botanical Gardens with her stepmom and her half-sisters last July 13. Here are pictures of what Rachel Bilson wore for the family day and of course, the chain strap cross body purse that she carried:

I already gave away what Rachel Bilson’s purse is in the title of this post. It’s the Rebecca Minkoff Alligator Impression Boyfriend Mini Bag in Grey Alligator:

Other colors/materials are Black Alligator, Pale Grey Leather, Tomato Nubuck and  Olive Nubuck (I’m partial to this Grey Alligator color too though). Purchase this bag for $325.00 at Shopbop.com.

If Vanessa Hudgens has the Alexander Wang Diego Bucket Bag, Hilary Duff has the Alexander Wang Rocco Mini Duffel.

Hilary Duff has been spotted carrying her latest handbag craze everywhere and the most often was, believe it or not, to the gym. Check out some of these recent Hilary Duff sightings with her Alexander Wang duffel bag in tow:

July 1, 2010 – Sisters Haylie and Hilary Duff out in New York City

June 8, 2010 – Hilary leaving a local LA gym with beau Mike Comrie

May 29, 2010 – Hilary grabs an iced drink after a morning run around the Los Angeles, CA area

Hilary Duff’s Alexander Wang bag is gorgeous – it is the IT bag of the moment after all – but I wish Hilary would stop wearing those grey pants with it. Okay she’s seen with the bag at the gym most of the time and those pants may be her favorite gym pants, but she has no excuse for wearing them again to dinner in the May 28 picture.

Hilary Duff, I love you and how you’ve protected your squeaky clean image and all, but it would be nice if you shake things up a bit from time to time even if it’s just in fashion.

The Alexander Wang Rocco Mini Duffel is $875.00 and can be purchased through Shopbop.com.
