ready to share the sex of her baby! 

The "Jersey Shore" star posted the cutest video with her son Lorenzo on Thursday, where the twosome revealed if the red-headed beauty is having a baby boy or baby girl.

Check out the video above to see their announcement.

We're so excited that the reality star will be having a little girl -- we can't wait to see her dressed up in zebra and leopard printed-clothing!  

As for little Lorenzo, he looked less-than-excited ... but he did seem pretty into those pink balloons!
