Jessica Simpson turned 31 over the weekend, and the young mogul was beyond thrilled to get a new orange Hermes Birkin bag from her fiance Eric Johnson. Lucky girl!

The birthday girl Tweeted:

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

Oh, Jess! We also love how she's wearing her favorite green sweater. Read what else she Tweeted about her special weekend ... after the jump.
