Michael Douglas' eldest son welcomed a daughter with his girlfriend, yoga instructor Viviane Thibes, on Monday, sharing the good news via Instagram.

"Today my appreciation for Mother’s all over the world has reached new I took part in a miracle as my baby girl was introduced to the world through a beautiful Amazon warrior...I’m so proud of you," he wrote alongside a photo of Viviane in a yoga pose with her very pregnant belly exposed. He also added the hashtag, "#iloveyou."

Earlier this month, ET caught up with Cameron at the premiere of his step-mother Catherine Zeta-Jones' new movie, Cocaine Godmother, where the 39-year-old actor spoke about what he was most excited about as an impending father.

"I'm really looking forward to it, and I think it's going to be more inspiration and drive to really try to put a nice life together for my daughter," he said, adding that though the couple had been thinking of names at the time, they were keeping them to themselves.

As for Michael, he was also looking forward to a major new role: grandparent. 

"I'm going to be a grandfather this month, before the end of the year. I'm very excited. It's about time," the 73-year-old actor told ET at the premiere.

Though Cameron has had a rough few years, he seems to have turned things around since being released from prison early in August 2016 after serving nearly seven years on drug charges. In fact, he and Viviane happily shared many posts to Instagram during the pregnancy.

ET has reached out to Cameron's reps.

Congratulations to the new parents!
