We've heard, and seen, former Olympian Bruce Jenner wear Spanx. We've also heard those sex change rumors, which are reportedly not true, according to estranged wife Kris Jenner. And now we're learning that Kendall and Kylie Jenner's dad wears a sports bra?

This definitely isn't helping those gender reassignment rumors die down.

"While out having lunch in Los Angeles with his daughter Kylie Jenner, the onetime 'world's greatest athlete' and Olympic decathlon champion was seen wearing a sports bra beneath his shirt," International Business Times noted.

"Bruce was dressed in casual attire: light blue running shorts, an athletic T-shirt and sneakers, and he kept his famous ponytail through the loop of his baseball cap. While it certainly looked like Bruce was wearing a 'sports bra' under his shirt, it is possible that it was a skin-tight tank top -- or that the photos were altered to make Bruce look like he had 'man boobs,'" Inquisitr speculated.

Indeed, the photos do show a faint outline of what appears to be either a tank top or a sports bra. Check the images here.

Despite being estranged from wife Kris and having confirmed his divorce from the Kardashian matriarch, Bruce was still wearing his wedding ring in the said photos. Force of habit or still can't let go?

Meanwhile, Just Jared said that Kylie had chosen to hang out with her dad Saturday instead of traipsing about in Europe with sisters Kendall and Kim Kardashian and mom Kris for a succession of fashion weeks in the continent. It was this father-daughter bonding session that was caught on camera and got people noticing Bruce's brow-raising underwear.

Could this be why the former athlete had chosen to wear his ring on such an occasion?

Aside from his questionable underwear, not much has been reported about Bruce's alleged sex change process. He has not confirmed anything about this rumor and Kris had already debunked such speculations. A source had previously told InTouch that his various appearance-enhancing projects - growing his hair out, getting a tracheal shave, having laser facial hair removal - were actually motivated by vanity, and not because he wanted to be a woman.

"Bruce has been obsessed with beautifying himself for years. It's a by-product of being surrounded by vain women - he likes to be pretty" the insider was quoted as saying.

He hasn't caught on the selfie bug that the rest of the Kardashians are known for yet, though. What's your take on Bruce's "moob" management strategy?
