Iman shares photo of her and David Bowie's rarely-seen teenage daughter

It's no surprise David Bowie and Iman's daughter is quite a looker!

Iman shared a rare photo of her 16-year-old daughter, Lexi, over the weekend -- and she's all grown up and gorgeous.

"My Sunday boo! #LexiLove," the 61-year-old model captioned the photo. The teenager looked absolutely flawless with her eyes closed, heavy winged eyeliner, a nose ring and painted red lips.

Iman has kept her daughter out of the public spotlight (for good reason) but she does share photos of her kiddo once in a while.

The last snapshot she posted was a sweet throwback collage that honored her daughter's 16th birthday and seemingly paid tribute to her late musician husband. One photo showed David on his own 16th birthday back in 1963, while the other was when Lexi was just a newborn in 2000.

"Lexi, as she's known to her friends and family, is pictured here with her parents as a new-born baby back in 2000. The main pic is of her father in 1963, an ambitious 16-year-old himself with a particularly bright future ahead of him. Happy Birthday Lexi, here's wishing you love 'n stuff from everybody here," she sweetly wrote.

Iman has also frequently shared sweet photos of David since his death in January 2016. On Valentine's Day, she posted a romantic black-and-white photo of her kissing her longtime love.

"My forever Valentine #BowieForever #ValentinesDay," she captioned the adorable photo.
