Gaga the latest star to grace the Gossip Girl set??? OMG!!! XOXO


We know those Upper East Siders love their fashion, and they're going to get a serious style injection from the newest celeb to film a cameo - none other than sartorial mentalist Lady Gaga!

We're not sure quite how she fits into the plotline - a sale shopping war with Blair? A snog with Chuck? An electro dance off with Nate and Dan? - but we can't WAIT to see her pulling her mad shenans onset.

What do you think she'll get up to? Comments please!
