Christian Bale is known for his extreme on-screen body transformations — but for his 50th birthday, the dude’s reached a great middle-ground … looking super ripped and toned.

The Oscar-winning actor was photographed Monday ringing in the big 5-0 down in Mexico — Cabo, to be specific — and like we said … the guy was definitely ready to show off his huge guns for the cameras, ’cause he was hanging out on the balcony without a shirt on.

He was also wearing a towel around his waist at one point too … big-time thirst trap vibes.

Eventually, CB popped on a top, hat, and shades to shield himself from the rays … making his way down to a beach with his wife, Sibi Blažić, and their nine-year-old son Joseph. We’ll say this about him … even when clothed, Christian puts other dad bods to shame.

Christian and Sibi are also parents to daughter Emmeline, 18 … although, she didn’t appear to be on the family getaway here.

The Hollywood actor is clearly making the most of his downtime after taking a bit of a breather on the career front — his only 2023 credit was voiceover work for “The Boy and the Heron” … and he currently has nothing in the pipeline this year.

Granted, he’s still one of the most prolific actors working today — and he’s still killing it at this point in his career. He can most certainly afford to take a break from on-camera work.

Lucky for us (and everyone else) … he’s right here putting on another type of show, no general admission tickets needed either.

Happy bday, Christian … you’re a gem, sir!
