"Dear Hayden, You looked beautiful last night. Thank you for the kind words. Much love, Tom," read the sweet message that accompanied the bouquet of white roses.
It transpires that Hayden actually bought her dress, unlike the majority of A-listers who typically borrow creations for the red carpet.
But Tom has a rule of dressing only one woman per awards show and Naomi Watts was already wearing a gold shimmering column gown designed by him.
It is thought that Hayden spent around $10,000 on buying the monochrome dress complete with side split and spaghetti strap halterneck.
Talking to Guiliana Rancic about her outfit on the night, Hayden said, "Tom Ford. It's the first time I've ever worn him, because I've been begging… I feel sexy in it, I feel comfortable in it, and I'm in Tom Ford.
"I would wear a plastic bag if it was designed by him."
Tweeting the flowers and the note, Hayden wrote, "Such an honor to wear one of this man's masterpieces! Thank you for my beautiful flowers!"
