'I’ve been around for so long it’s like dog years, I feel like I should measure my life in dinosaur years! I feel like I’m actually 1000 years old!' Griggs joked.
She added, 'However in actual fact I’m 44, Todd [Griggs' husband] turned 44 on Friday. We’re so excited that we are young parents…we now have these grown-up adult gorgeous young men in our lives.'
'To be young grandparents and be young enough to do things with them and to be able to help them out...I think it is awesome.'
The Better Homes & Gardens host said her husband is 'obsessed' with their grandson Jax.
'I’m excited but Todd is next level,' Griggs explained.
'He’s never been around babies. He’s just obsessed. He has actually replaced me on his phone with a picture of the baby,' she said.
Griggs is clearly smitten too, however, regularly posting sweet snaps of the bub to her social media pages.
Earlier this year Griggs told TV Week she was thrilled when she found out she was going to be a grandmother.
'Oh, man — we were that excited. You’ve got to remember I had children young too [Joe was born when she was 22], so it was such a great thing and so exciting,' she told the publication at the time.
