Jessica Simpsons 31st birthday was yesterday, and she was so excited about the present her fiance bought her with her money that she went on twitter to post a picture and say:

Eric made my birthday!!! I have never been more surprised in my life! Jackie O who? ;)

That’s a purse, by the way. If you couldn’t tell. It’s from Hermes. It’s called a Birkin. They start at around $8,000 but can easily reach $150,000. They come in 4 sizes (20, 30, 35 and 40 centimeter), and are usually made of either leather, ostrich, crocodile, or lizard skin. Victoria Beckham has spent around $2.3 million on them.

Jessicas looks like a 40cm leather bag, so it probably cost around $15,000. She’s actually really well known for her extensive and extra fancy bag collection (though she usually carries Louis Vuitton), so she’s either acting so happy to be polite or because this is actually a Birkin shaped cake.
