Would you rather see Ashley Parker Angel wear it all ... or nothing at all?

The former O-Town singer has been sharing a ton of half-naked photos on his Twitter page recently, including the just-uploaded Calvin Klein shot above. "Happy Hump Day," he captioned the pic, along with the hashtags "#fitnessaddict #fitspo #determination #gym."

The 32-year-old has been on a health kick this year, saying he's "committed to getting in the best shape of my life in 2014" on his Instagram page. "Though I'm not exactly where I want to be yet - I'm as committed as ever to getting there." 

Parker's old boy band recently reunited without him and even released some brand new music.

Trevor PenickJacob UnderwoodErik Michael Estrada and Dan Miller recently reunited without Angel and released their first new song in over a decade, "Skydive," back in May. 

"We had discussed a summer tour to perform our old songs and finally give the fans what they’ve been asking us for the last 10 years. However, once we began working, what developed was something a little more ambitious," Jacob told Billboard earlier this year. "The ideas kept flying and we couldn’t help but start making new music."
"Each of us have different reasons for agreeing to do this again, a decade later. Mine has to start with the fans. I never knew how much I would miss them. I never quite realized how much of an impact we had on them," added Erik.

Their new album, "Lines & Circles," is out next month.
