This September they will celebrate their two year anniversary.

And Blake Lively and Ryan Reynolds have clearly found their rhythm as a couple as they arrived to the Cannes premiere of The Captive wearing matching black and white ensembles.

On Friday the duo were seen on the red carpet looking every bit the glamorous Hollywood power couple, exuding movie star charisma.

The 37-year-old actor – who married the blonde beauty in September 2012 – looked to be even more smitten than ever with his wife.

The Wolverine star could not take his eyes off the Gossip Girl alum, 26, as she posed for snaps on the red carpet.

And it was easy to understand why he’d be so taken with the actress, as she was positively gorgeous in a long flowy monochrome gown.

The strapless frock displayed her alabaster complexion, as she pinned her hair in a glamorous part with a swept to the side bun.

Ryan was equally fetching in a dapper black and white tuxedo, which featured a white bow tie adding a touch of flair to the refined ensemble.

Directed and co-written by Atom Egoyan, The Captive is a Canadian abduction thriller in which Reynolds plays Matthew, a landscape gardener whose daughter Cassandra was kidnapped while walking through a car-park eight years previously.
