Blake Lively, Lady Gaga sparkle at Barneys holiday event

Lady Gaga recently opened the "Gaga Workshop," her own version of Santa's Workshop. As you can imagine, the event, which she is working on with Barneys New York, is a little bit stranger and a lot more glamorous than the North Pole's workshop, but it's still filled with plenty of holiday cheer.

A number of stars attended the opening, including Mother Monster herself. One starlet that really stood out among the others was Blake Lively. The Gossip Girl wore a striking cobalt two-piece suit that was both sensible and sexy. The low cut top had a unique design at the shoulders that allowed her to show off some skin, but what really impressed were her baubles.

Lively wore giant, sparkling rings on both her hands. On her right, a thumb ring added the necessary glitter this outfit required, while her left held a rather pointy ring that complemented her getup.

Not to be outdone, Gaga herself was there with her own brand of bling. Her personalized jewelry consisted of thin sterling silver bracelets decked out with charms.
