Tyler Baltierra Gains 10 Pounds and Tweets a Steamy Shirtless Pic — Hot or Not? (PHOTO)

Our love for Teen Mom's Tyler Baltierra knows no bounds. He's sweet, charming, has a slightly deranged obsession with all things Batman, and oh yeah — did we mention that he's rocking a seriously studly body?

Tyler's always been a bit of a beanpole, but he's been bulking up at the gym and recently put on a whopping 10 pounds!

"Gained 10lbs in 4 months" Tyler tweeted along with a sultry shirtless pic. "With my metabolism that is a miracle! #prettypumped."

Va-va-man-voom! We've never seen Tyler look better, and we're especially fond of his epic necklace. Basically, he's making love to the camera, and we approve. So, what does Catelynn Lowell have to say about her man's transformation?

"Man U fricken hottie!!" Cate tweeted "I told him now he has to model like this for me lol whenever I want!!"

Sigh, these two. Good to know they still have the hots for each other after almost nine years of dating!

What do you think of Tyler's new look? Swoon yourselves silly in the comments!
