It's a boy band battle ... or is it?!
O-Town star Erik-Michael Estrada took to Twitter on Tuesday to encourage men to get checked for testicular cancer, but he also seemed to throw some shade at former bandmate Ashley Parker Angel at the same time.
"Support the cause. But what ever you do don't look at my abs. Or how low under wear is. Or my junk," he captioned his shirtless selfie. In the pic, the teen heartthrob is posing for a picture in the mirror, wearing only a low-slung pair of striped boxer briefs.
Seems innocent enough, until you see the photo Ashley also recently tweeted out (above right).
Angel shared a similar shirtless snapshot last week, but he took it one step further and grabbed his bulge. "#FeelingNuts for Check One Two raising awareness for testicular cancer. Don't forget to check yours," he captioned the pic.
The #FeelingNuts hashtag hasn't quite gone as viral as the Ice Bucket Challenge, but Hugh Jackman and Ricky Gervais have joined the social movement to raise awareness of testicular cancer.
If Erik was realllly supporting the cause, he would have grabbed that junk!
These racy photos are nothing new for Angel, who's been sharing a ton of half-naked pics on his Twitter page recently, including the recently-uploaded Calvin Klein shot above.
"Happy Hump Day," he captioned the pic, along with the hashtags "#fitnessaddict #fitspo #determination #gym."
toofab's Brittany Kyles recently sat down with the band, where she put them on the spot about Parker's revealing pics. See what they said in the video below!
Estrada may be trying to steal some of Ashley's thunder ... or it could all be for a good cause. Do you think there's a feud brewing? Tell us what you think in the comment section.
