The 'Jurassic Park' actor Jeff Goldblum is set to tie the knot with Emilie Livingston - who, at 30, is 31 years his junior - after popping the question in Hawaii earlier this month.
Emilie, a former Olympic rhythmic gymnast, used social media to reveal the good news.
Clearly emotional, she wrote on Twitter: "Jul 8 he proposed @ our fave #okstore. I was taken over by tears of joy n ecstasy! We picked the ring 2gether #inlove (sic)"
She later posted several photos on Instagram, including a close-up of her engagement ring as well as a photo of the pair embracing one another.
She captioned it: "So in love!!! #jeffgoldblum #emilielivingston #love #initforlife"
Jeff, 61, has been married twice before, firstly to Patricia Gaul, who he wed in 1980 but split from six years later, a year before tying the knot with his 'Fly' co-star Geena Davis.
The second union lasted just three years.
Although he hasn't yet spoken out about his latest engagement, the 'Independence Day' star has previously described Emilie as "just spectacular and beautiful."
He added: "I'm happy as a clam with her. I feel lucky, lucky, lucky."
