You might've peeped Lady Gaga (and her pup!) on the cover of Harper's Bazaar yesterday, but today the mag released even more insider info—including pics of Mother Monster decked out in head-to-toe couture ensembles (next to an interview with Karl Lagerfeld, no less). While Lady Gaga sported her signature Chanel and Dolce & Gabbana pieces for the spread, we noticed one designer in her photo shoot that we hadn't seen before: Natali Germanotta, aka Gaga's little sister!

Lady Gaga wore a handmade, all-white slouchy shearling jacket by Natali paired with platinum-blonde braids, super-thick brows, and ripped nude fishnets. Gaga proudly supported her sis on Instagram saying, "And my sister Natali killing it in fashion, jacket from her Parsons thesis collection chosen by Carine Roitfeld to be featured this Icon Issue. Natali made it by hand. #germanottagirls."

Natali also expressed her excitement about the featured jacket and said, "Thank you @harpersbazaarus @carineroitfeld @ladygaga and Stephen Gan for believing in me! This is the best day of my life #vertigo #crackle." Awww, now that's love! To see the full interview and more photos from the spread, head to harpersbazaar.com.
