PARIS: Upstaging a Louis Vuitton show is hard, but somehow Miuccia Prada managed it, thanks to Lupita Nyong’o and Jared Leto.

The Oscar winning pair — whose exact relationship is the subject of speculation — were both invited by the Italian designer to attend her plastic-wrapped fall-winter Miu Miu show in Paris.

And if that wasn’t enough attention-grabbing, Nyong’o had to move seats in order to fit a tardy Rihanna in a fur leather jacket in the Miu Miu front row.

Meanwhile, former Balenciaga designer Nicolas Ghesquiere gave an admirable debut at Louis Vuitton attended by Princess Charlene of Monaco, Catherine Deneuve and Charlotte Gainsbourg.

But the ghost of Marc Jacobs’ Louis Vuitton past lurked.

Even before Jared Leto thanked “my future ex-wife Lupita” in a speech at the Independent Spirit Awards on Saturday, there’s been speculation that he and fellow supporting role Oscar winner Lupita Nyong’o have been an item.

The “12 Years a Slave” actress has laughed it off — most notably on The Ellen Show — but has not denied it. Now, to further fan the flames, both stars were at Paris’ Miu Miu show at the same time — and both nursing jet lag.

Nyong’o, who said she “really liked the show,” looked radiant in a clean Miu Miu jacket with an off-white sparkling embroidered collar.

But Leto wore shades and admitted he was exhausted.

“But it’s the best kind of tired you could ever imagine,” he said, avoiding comment on the relationship rumors.

With a pinch of irony, Senora Prada wrapped the entire show venue — Paris’ Environmental Council — in non-biodegradable plastic.

It was full of young, fun and colorful suggestions on how to keep warm and dry during fall and winter.

See-through pale blue PVC skirts came alongside a bright yellow raincoat with sporty tassels.

Or waterproof sheer red hooker boots that somehow remained classy were mixed up with skiing shades and quilted pastel ski jackets.
