Mike is showing off his new and improved sculpted body.
In this clip from Sunday's Revenge Body With Khloe Kardashian, Mike meets up with Khloe Kardashian and stylist April Roomet, who instantly noticed Mike's more toned figure.
"It looks like you've been doing some sculpting. You've got a good arm under there," April told Mike.
The now-confident Army veteran was not only walking around with his shirt off, but was willing to try some bold prints and styles that would surely make him the center of attention at his big reveal.
"You have so much confidence now, I love it!" Khloe exclaimed. "You better walk around with that shirt off!"
When it comes to showing off his new look, Mike is hoping that some important people from his past are there to see it.
"I'm hoping my ex-fiancé and my old friend Rob show up so that I can show them I'm a new, better version of myself," Mike declared.
See Mike get his swag back in the clip above.
