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.

Hot new actress Nikki Reed took some time off from promoting “The Twilight Saga: Eclipse” and was spotted just chilling out with her “brother” Nathan in New York last July 6.

I put that in quotes because although celebrity gossip sites have identified this guy as Nikki Reed’s brother, they were seen heading into a tattoo parlor and coming out with matching bandages on their forearms that day. I don’t know, I just find that kind of strange. Do you? Maybe I’m just not the type to walk arm-in-arm and get tattoos together with my brother.

Anyway, cute outfit Nikki Reed!
