Mystery Sender of Cardi C's 'Tom Petty' Flowers Revealed

EXCLUSIVE

Cardi B did not get flowers from the great beyond — as she insinuated by thanking Tom Petty for a Grammys bouquet she received — but, TMZ has learned who REALLY did the honors.

Sources tell us … celebrity florist Annie Wonderlich, owner of Art Fleur, sent the bouquet wishing Cardi luck at the award show. We’re told Cardi is one of her clients, and Annie also delivered a Grammy arrangement to Lady Gaga.

After getting the flowers, Cardi looked at the back of the card — which contained a Petty lyric — and thought they were from him. She thanked Tom on social media … prompting the internet to quickly point out that would be pretty freakin’ amazing (as in, impossible) since TP sadly died nearly 2 years ago.

Although, we’re sure Ghost Tom’s probably a Bardi fan.

The sender’s true identity was there the whole time … because the other side of the card had a note from Annie reading, “Cardi B! Wishing you LOVE, LIGHT & LUCK tonight at the Grammys! All the best! XOXO, The Art Fleur Team.”

We’re told Annie’s company has TONS of celeb clients, including Kim Kardashian i Taylor Swift, and every special delivery comes with a card quoting someone famous — like Oscar Wilde, Claude Monet, David Bowie, and in this instance, Petty.
