Apparently, Lanvin's Alber Elbaz would take his place. In turn ex-Nina Ricci designer Olivier Theyskens would replace Alber. The designer musical chairs is still only a rumor but keep your fingers crossed anyway.
We know that you are an icon and can basically do whatever you want from this point on but, we beg you, Karl: please don't go. (in French below just in case...)
Nous savons que tu es une vedette and que tu peux, en fait, faire tout ce que tu veux à partir de maintenant, mais nous t'en supplions Karl: s"il te plait, ne t'en va pas. (French)
If in the end this rumor turns out to be rubbish, we'll be happy. But for the record, to whomever started this rumor: you are NOT funny!
