Iman is celebrating her milestone day as she plans on "aging gracefully."

On Friday, July 27, the supermodel took to her Instagram account to mark her 70th birthday and posted a sweet clip of her and a throwback note from her late husband

In the celebratory post, the model posted a video in which a cell phone, a white icing fruit cake with seven and zero number candles, was decorated on it, along with a pink flower vase on a table.

On the screen of the cellphone, her video popped up in which she came closer to candles and blew them up in the video.

"B****, 70 is the new 70! Aging gratefully #IMANHBD," she captioned her post.

In another post, Iman uploaded a photo of a letter written by her late husband, David Bowie, back in 2015 on her 60th birthday.

"Happy birthday darling! 60 years. It's been a privalige [sic] to have shared over a third of these with you. I love you! David — hubby xx," the note read.

"My last birthday card from David. July 25th, 2015," the snap of the note.

In a follow-up post, Iman penned down that she is "grateful for another trip around the sun."
