Monet exhibition (Paris)

Salut!

I'll be in Paris on the weekend Protected content and would like to visit the Monet exhibition. As it is so popular, I guess that lines tend to be very long... Unfortunately, all online tickets are sold out for those dates. Does anyone know if there's another possibility to get tickets in advance? What time should I be there to avoid long waiting times?

Thanks for your advice!!
