Katy Perry's New 'Part of Me' Clip - Watch Now!

Katy Perry rocks a sheer LBD while leaving the Gansevoort Hotel on Thursday (May 24) in NYC.

The day before, the 27-year-old pop star performed for troops at Pier 9 in Brooklyn during Fleet Week.

“I think if anyone deserves a party, I think it’s probably the people in service. They are the ones that are actually deployed and protecting us from all the bad guys, and they deserve to celebrate, and they deserve to be celebrated,” Katy told MTV News.

Katy also recently released a new clip from her Part of Me 3D movie, which features her sister Angela Hudson. Check it out below!
