“Dannielynn b4 she raided the dessert room at the Barnstable-Brown Party where I met her Mom in 2003 #lifefullcircle #BarnstableBrownParty,” Birkhead, 44, tweeted on Saturday as he posed alongside his daughter.
Birkhead, who works as a photographer and dabbles in real estate for a living, has raised his daughter — who looks just like her mother — as a single dad. Dannielynn was only 5 months old when Smith, a former Playmate of the Year, died at age 39 following a drug overdose in Florida in 2007.
In February, during a sneak peek on Good Morning America of a new 20/20 interview, Birkhead shared a sweet letter the 10-year-old wrote to explain her love of coloring and how it connects to her mother.
“Ever since my mother’s death, a friend of hers said she would send me pretty butterflies,” Dannielynn had written. “So, butterflies chase me everywhere and I let the butterfly come out of my pencil and fly on my paper with its wings of love.”
