Tim McGraw inspired hundreds of excited tweets when he appeared on "The Ellen DeGeneres Show" Tuesday to promote his new album.

The country star came to talk about his new music and promote his latest, “Two Lanes of Freedom,” which includes a duet with Taylor Swift, but instead he seemed to focus on his body.

Their single, "Highway Don't Care" has just been released. 

Swift tweeted: 

"I sang with Tim McGraw on a song on his new album- it's called 'Highway Don't Care' and it's out now and I'm psyched about it- check it out?"

Though a Swift-McGraw collaboration is big news, fans were hooked on what had just happened on "Ellen" and kept their comments strictly about the 45-year-old singer.

McGraw recently revealed that he’s been sober for nearly five years and has subsequently traded in taking shots for shooting hoops -- all for his children’s sake.

The healthy living choice seems to have done wonders for his body and he made sure to let the whole world know just how fantastic he looks.

The award-winning singer took off his shirt to reveal a hard six-pack and simultaneously made women across the country squeal.

Many took to the Twitter accounts to publicly swoon over McGraw and his new shape:

@K_Fyfe929 wrote, “I can't even handle Tim McGraw on @TheEllenShow right now #HolyHottie #SoBuff.”

@shaylaasmith  tweeted, “Tim McGraw is honestly more attractive than ever. #ellen.”

@ShannieDaze was happy McGraw decided to go on DeGeneres’ show and thanked the host:

“Tim Mcgraw..you just went on the top of my list #handsome #thankyouellendegeneres.”

‏But taking off his shirt wasn’t the country star’s only reveal, he also shared he wasn’t wearing any underpants since his jeans were too tight. Click here to watch the singer tell DeGeneres about not wearing underwear. 

Of course, plenty of people had something to say about McGraw’s fashion choice. 

@Weso428 tweeted:

“So Tim McGraw goes commando in jeans... Ditto my friend Ditto”

@PattiMitchell68 wrote about the cowboy:

“@TheTimMcGraw sober, sportin’ a six-pack, and going commando! You’re welcome, ladies.”

@NaNeeNo talked about how fantastic he looked, regardless of age:

@ladyaer12 shared one of the jokes McGraw made about his physique:

"’Look at my stomach it's like a muscle jacket.’ - @TheTimMcGraw Dying!! Lol”

“Two Lanes of Freedom” is in stores now.
