Paris -

They're a couple rarely seen in public, together only since February.

So when Academy Award-winning power couple Charlize Theron and Sean Penn walked in to Dior's Monday show, holding hands, and took seats in the front row, it wasn’t only the couture gowns that dazzled guests.

Theron, 38, a brand ambassador for Dior, wore a gold shimmering fringed cocktail dress similar to the one she appears in for Dior's now-iconic J'Adore perfume advert.

She and 53-year-old Penn, who wore a black Dior suit with open shirt, chatted with LVMH boss Bernard Arnault.

That held up the show, but that didn't seem to help another Oscar-winning guest who was running late.

Hunger Games star Jennifer Lawrence ended up having to catch a repeat of the show later in the day because her flight was delayed. - Sapa-AP
