Justin Bieber just can't keep his shirt on. And we're not complaining!

Despite certain relationship-related events, Justin Bieber is certainly is having a srs moment in the spotlight. (But has he ever stepped OUT of the spotlight?) Following his recent breakup with Selena Gomez (we're almost done drowning our sorrows in the Häagen-Dazs...almost) and performing Justin Timberlake's classic 2002 breakup hit "Cry Me A River" in Boston, AND observing his RyGos pecs in the mirror, Biebs is BACK and more shirtless than ever. Just can't keep those abs under wraps, can he? WE. ARE. NOT. COMPLAINING.

It's hard to know how Justin is doing emotionally ever since the split (singing JT's über-famous breakup song says one thing, but eyeballing Victoria's Secret models says another), but he DID post this VA VA VOOM Marky Mark-esque underwear model photo on Instagram with the caption, "What song is next." Judging by this picture, it's probably "Tearin' Up My Heart" or "I'm Too Sexy" or "When The Lights Go Out" (never forget 5ive, guys) or some such grindin' on the dance floor jam, because, er...is it getting hot in here? Perhaps the caption should've read, "Greetings, LADIESSSS."

Consider JB's transformation into Marky Mark...complete.
