Watch out Lindsay ... there's a new acting Lohan in town! Lilo's brother Michael Jr. is getting gritty in this new short film called Razors and Balloons.

We'll admit, Lind's bro looks mighty fine when he takes off his shirt towards the end, but the overall concept is a bit odd. Perhaps taking that sexy bod into the modeling industry may be a better bet.

Great to see Mr. Lohan using his talents wisely. Gotta love his ability to open beer bottles with his teeth. Cheers!

In case you missed our photos of Michael Jr. shirtless on the beach ... check him out after the jump.
