Larry Birkhead continues to smile when thinking about Anna Nicole Smith.
The former Guess model died on Feb. 8, 2007, after being found in a Florida hotel room. Toxicology report later determined she died of an accidental overdose of prescription drugs.
Fifteen years later, Larry focused on the good times while honoring his ex-girlfriend.
"Still remembering this one 15 years after her death," he wrote alongside a throwback of him snuggling up to Anna. "She was truly one of a kind. She struggled for love and acceptance. Just when she found a little piece of one or the other, life seemed to sabotage."
Larry often uses his social media to pay tribute to Anna, and he consistently references the model while speaking about Dannielynn, the 15-year-old daughter they share together. Anna died when Dannielynn was merely five months old.
"Today, I remember your heart, your soul and your beauty, both inside and out," Larry said in his Instagram message. "Your love is alive still to this day, in the form of a truly one of a kind teenager with her Mom's smile, beauty and courage. Thanks to Anna's fans for helping keep her memory alive. We love you Anna Nicole.
He added the hashtag "if mom could see you now," a clear nod to their daughter.
