Ryan Reynolds sent fans into a frenzy over his adorable reaction to his wife Blake Lively's dress reveal at the Met Gala.
Blake always brings the best looks to the Met - so we weren't surprised when she pulled it out of the bag again this year.
The Gossip Girl actress, who is a co-chair of this year's event alongside her husband Ryan, stunned on the steps of the Metropolitan Museum of Art in a showstopping custom Versace dress, for the night's theme: 'In America: An Anthology of Fashion' and the 'Gilded Glamour' dress code.
The gorgeous copper strapless number was paired with matching gloves and a pair of emerald earrings and a dainty tiara.
But nothing could have prepared us for the surprise she had in store. Crew members appeared out of nowhere to remove the hefty bow from the dress, making it transform from pink to blue in the blink of an eye.

Everyone was stunned by the iconic colour-changing dress, but her husband Ryan's reaction was truly too sweet for words.
Ryan was seen looking on from afar as the glam squad rushed in to remove the bow, and at the very moment the fabric from the sash revealed the second look of the night, his jaw dropped.
He later could be seen beaming proudly and clapping as members of the crowd applauded the impressive display.
On Twitter, users praised Ryan for his adorable reaction, as one person said: "If he doesn't look at you the way RYAN looks at BLAKE, girl he is not the one'.
Another wrote: "Ryan Reynolds's reaction to the unveiling of the change to Blake Lively's gown is EVERYTHING."
A third commented: "Ryan Reynolds and Blake Lively are just [heat emojis]. The way he looks at her, and she's just goals all over."
Someone else put: "Ryan Reynolds reacting to Blake Lively's dress reveal... put a fork in me... STOP BEING SO F****ING ADORABLE."
On the red carpet, Blake explained the meaning behind the incredible dress — and why it fit with the theme of the gala perfectly.
"So I arrived in copper and then it [patinated] to a verdigris," she said, referring to how copper turns green when exposed to oxide compounds — like on the Statue of Liberty.
"This is the constellation from Grand Central Station,” she said, as she pointed to one area of her dress. "This is architecture from the Empire State Building — the Statue of Liberty. It’s, you know, lots of little references to New York City," she said, pointing to another.
