Happy birthday, Patrick Schwarzenegger!

The blue-eyed cutie is celebrating his 22nd birthday today, and such a special event wouldn't be complete without a little throwback action from your nearest and dearest, right?

Patrick's mom, Maria Shriver, and older sister, Katherine Schwarzenegger, helped ring in his big day by taking to social media and sharing some adorable childhood pics of the actor with sweet words for his b-day, while Arnold Schwarzenegger revealed what special event he and his son participated in this morning to celebrate.

"Don't cry, it's YOUR BIRTHDAY!!! Happy happy birthday to my amazing brother @patrickschwarzenegger !!! I love you tons! Time to celebrate!!," Katherine wrote, alongside a funny picture of her little bro hysterically crying while being kissed on the cheek. She also hilariously added the hashtag "#freethenipple" because his overalls shifted and showed us some extra flesh, LOL.

Meanwhile, Maria took to Twitter to spread the well wishes for her son's birthday, and shared two separate posts.

Following in Katherine's footsteps, she also posted an old photograph of Patrick as a young boy, giving the camera a solemn look. "Smile! It's your 22nd birthday and you are the best! Son I love you soooo much @pschwarzenegger."

She then proved that Patrick does smile in pictures, sharing a snapshot of him grinning while next to his famous mama. "Now you are smiling! Happy birthday to a loving, kind, fun, smart, caring man. Yeah @PSchwarzenegger!!"

Of course, his dad got in on the action, too. And in true Arnold fashion, he chose to take his son to the gym for his birthday (and it looks like Patrick is workin' on those gains!).

"Happy birthday @PSchwarzenegger. I never thought I'd have a son who was stronger and smarter than me," he wrote along with a video of Patrick working out and then flexing his bulging bicep. Seriously, those guns are no joke!

 

"What happens when you stay out late to celebrate your birthday... @Schwarzenegger picks you up at 7AM to workout," the newly 22-year-old wrote.

Have a great birthday, Patrick!
