On the 11th day of Gaga, Barneys New York is giving us the Lady Gaga Playbutton mp3 player. Barneys New York is partnering with Gaga’s Workshop to ring in the holiday season with 12 days of Gaga, and day 11 is bringing the tech. The punk-style button pins onto your clothes with a safety pin, and doubles as an mp3 player with the controls on the backside and a headphone jack on the bottom. It looks like it could be a little bulky and heavy for a pin, but that’s a small price to pay to rock the Gaga swag. If you’re a big Gaga fan, you can sink your nails into the Lady Gaga Playbutton for $50 from Barneys New York’s website. While you’re there, make sure you check out the other days of Gaga. The 12th day is still coming up, and I’m guessing it won’t be drummers drumming (though with Gaga, I guess you never really know).
