“Happy Father’s Day to all the Dads out there! Of course we had to get here first, well because I’m old.”
Dannielynn was just five months old when her famous mum died at 39 in 2007.

It comes after she appeared with Larry at the Barnstable Brown Gala in Louisville in May, ahead of the yearly Kentucky Derby.
The teenager was the picture of her model mum as she marked the 20th anniversary of her parents’ meeting at the event.
Dannielynn even wore a shirt decorated with photos of the Playboy model’s Guess campaign, matched with jewellery she inherited from her mum after her death.

The model and actress made headlines in the early 90s when she married billionaire oil tycoon J. Howard Marshall when he was 89 years old. When he died just over a year later, Anna Nicole went to court to go after his fortune.
But her fame ultimately led to tragedy, as she battled addiction and the sudden death of her oldest child Daniel in 2006 - days after Dannielynn’s birth.
She died months later, after an accidental drug overdose.
