As if Lady Gaga is capable of having a low-key 30th birthday.
In addition to having just about every celebrity attend a party in her honor, she also wore a custom YSL dress gifted to her by Hedi Slimane himself.
Gaga posted a photo of her and Hedi to Twitter saying, "Thank u Hedi for this beautiful dress on my birthday, I felt like a rock n roll queen for my 30th @YSL Paris Couture."
And that she does. More specifically, a rock 'n' roll queen shrouded in designer gift wrap. Classic Gaga.
