Lady Gaga meets up with Irish milliner Philip Treacy in London last weekend.

Lady Gaga is touring Europe these days, touching down in London last weekend for a show at the 02 Arena which gave her a chance to catch up with one of her besties, the renowned Irish milliner to the stars Philip Treacy.

Based in London, Galway native Treacy and Gaga go way back. He’s designed many of the outlandish headpieces she wears, and she’s so taken with his work that she planned to do an internship with him a few years back.

“I feel so lucky the number of brilliant people that I've been blessed to know. Philip Treacy is in the genius category, both creative and kind. We laughed for hours last night, the best type of London moment, with those you love,” LG posted on her Instagram account with a pic.

Treacy is equally smitten with the lady. "She's a really fun person to work with. She has a different sensibility, a different idea of what's perfect and beautiful. She allows me to be really creative and brings my designs to a whole new audience,” he told Vogue a while back.
