'Today, my mother is 92': Alec Baldwin wishes mother Carol a happy 92nd birthday

Alec Baldwin led the way in wishing his mother Carol Baldwin a happy 92nd birthday Wednesday.

Alec, 63, took to Instagram with a picture of Carol as she sat on a recliner surrounded by festive balloons that included a unicorn and the numerals 92 to commemorate the occasion.

'Today, my mother is 92,' Alec captioned the shot. 'Unf***ing believable. Living proof that a diet of Brownies, Tab, @wegmans and @jeopardy will lead to a longer life. Happy birthday!!!'

Actor Billy Baldwin, 58, who is on location filming in Italy, sang Happy Birthday to his mother with the crew of the production he's working on.

He captioned the clip, 'My crew singing Happy Birthday in Italian to my gorgeous Mother Carol. 92 years old today. Miss you Mama! See you back when I'm stateside.'

Carol, a breast cancer survivor, is also the founder of The Carol M. Baldwin Breast Cancer Research Fund, a nonprofit that is aimed at supporting 'both new and established researchers investigating the causes, prevention and treatment of breast cancer.'

Alec, in his 2017 memoir Nevertheless, wrote about his mother's efforts with the charitable organization.

'Over the years, we began to joke about how my mother had become a bigger celebrity than any of her sons,' the actor said. 'We joked that she'd push any of us off a cliff for a photo op, now that she was the "celebrity."
