sunglasses Kaley Cuoco bra wedding ring spandex Ryan Sweeting

Talk about making a big bang!

Yesterday Kaley Cuoco went to yoga class in Los Angeles, and the 28-year-old actress showed off her fab physique in a pair of spandex and the skimpiest sports bra we've ever seen. Hey, no complaints here!

So how's married life treating the TV star? According to a recent report, things aren't so hot between Kaley and her hubby of six months, tennis pro Ryan Sweeting. Apparently the duo got into an argument at a friend's engagement party in Florida earlier this month, and a source tells Star mag that Kaley felt Ryan wasn't showing her enough attention so she started getting irritated.

"Kaley looked like she really didn't want to be there," the insider dished. "Ryan told her to relax, and that is when all hell broke loose. She snapped back and told him where to go. She didn't know that many people at the party and felt like he was being irresponsible for not looking after here." Hmm, seeing as they were posting all sorts of happy Instagram pics together, this seems a little bit hokey, right?
