While the Ocean’s 8 star wore a pair of elegant silver sunglasses, her main accessory was the bouquet of vibrant flowers in her hands.

The A-list actress rounded out her casual look with a pair of simple khaki-colored sandals.

A slew of fellow A-listers took to social media to wish the brunette beauty a happy birthday.

With his trademark humor, Ryan Reynolds shared a post from a nude scene he completed with the birthday girl in The Proposal film.

‘Happy Birthday to the inimitable and stunning Sandra Bullock. For your birthday this year, I got us both intimacy coordinators. And an HR department. And clothing?’ the Deadpool funnyman captioned the post.

Jennifer Aniston also joined in on the birthday fun, sharing never before seen photos of the Miss Congeniality star on her Instagram page.

‘Happy birthday Sand-A-La!’ the Friends star captioned the photo, revealing her loving nickname for her fellow Hollywood star and friend.

The Speed star has been a Hollywood mainstay for decades.

Dubbed ‘America’s Sweetheart’ after her roles in various popular rom-coms and action films, Sandra continues to act years after her film debut in the 1987 thriller Hangman.

Her most recent appearance was a vocal role in the Brad Pitt-helmed film Bullet Train.

Although the Bird Box star has been a movie mainstay for years, she revealed recently to CBS Sunday Mornings that she plans to take a break from acting for a while.

‘I can be creative, I can be part of a community, but right now, work in front of the camera needs to take a pause,’ the Unforgivable star said.

She emphasized that she didn’t want to give up acting entirely, just that she wanted to spend more time with her family.

‘I want to be at home. So I’m not doing anyone any favors who’s investing in a project if I’m saying, ‘I just want to be at home,’ she added.

Sandra also said, ‘I just want to be present and responsible for one thing.’
