David Bowie and Iman's teenage daughter, Alexandria, is strikingly beautiful

It's been a year and a half since David Bowie passed away, but he lives on through his wife and daughter.

Iman, who wed Bowie in 1992, celebrated their daughter Alexandria's 17th birthday with a photo of the gorgeous teen, calling her "the queen of my heart." Check it out: She has her mom's supermodel looks and her dad's edgy style.

Although she's certainly Hollywood royalty, Alexandria, who more often goes by Lexie, has stayed out of the spotlight. Little is known about her, and her famous mom rarely shares family photos online.

Bowie also has a son, Duncan, from his first marriage. Duncan's own son was born exactly six months after his grandfather's death.

In June, Iman commemorated what would have been her 25th wedding anniversary with a heartbreaking photo of Bowie kissing her on the forehead. Accompanying the photo is the quote, "I would walk forever just to be in your arms again."
