Jeff Goldblum, 70, says he's having 'such fun' as a father to two young children

Jeff Goldblum is having the time of his life as an older parent to his two young sons, five-year-old River and seven-year-old Charlie.

The actor, who turned 70 last month, shares his two children with wife Emilie Livingston, 39, and although it can be 'maddening' at times, Jeff says he's having 'such fun' with the youngsters.

Raving about the better parts of parenting, the Jurassic Park star said: "It's amazing, it's revivifying, and makes my relationship with Emilie, frankly, enhanced."

"Seeing her in this new role is unbelievable. She's heroic beyond imagination", he told Hoda Kotb on Today.

But, just because you're Jeff Goldblum doesn't mean everything comes easy. This guy knows a thing or two about the insanity that is parenting.

"It's challenging and it's sometimes maddening and very volatile", said the father-of-two.

"As you know, at 3 and 5, 5 and 7 they can be like feral creatures unleashed. Oh yeah, and sweet and amazing. It's great."

In an earlier interview, Jeff told iNews that he was 'glad' he waited to have children.

"It feels great to do it right now, because all the things I'm considering are perfectly suited to the big questions and challenges of having kids, and what you want to expose them to.

"What you want to leave them with, what life is, and what kind of life you contribute to them."

Jeff has been married to Canadian retired Olympic gymnast Emilie since 2014.

The couple didn't exactly have the most glamorous of meet-cutes, with the actor first bumping into his wife-to-be during a training session at the gym.

Speaking to Wired in a 2018 interview, Jeff recalled: "We were at Equinox on Sunset Blvd., the gym. I saw her from across a crowded room, and I marched up to her, entranced, and began some kind of conversation."

The pair have been happily married for eight years now, and share sons Charlie Ocean and River Joe.

Before he met Emilie, Jeff had been married twice - first to Patricia Gaul from 1980 to 1985, and then to Geena Davis from 1987 to 1991.

Jeff did also briefly dated his Jurassic Park co-star Laura Dern, but the pair eventually called it quits in 1997 after two years together.

It would appear there are no hard feelings between these two stars, though, since they were both happy to appear alongside each other in this year's Jurassic World: Dominion.
