— -- Kaley Cuoco is on vacation with her husband, Ryan Sweeting , and having some fun on Instagram.

The two clearly have bathing suits on underneath.

It's appropriate timing for the joke: Cuoco was one of the names of the dozens of actresses who were tied to the alleged nude photos that were hacked and leaked over the weekend. Some have speculated that this photo is, in fact, a response to the hack, though Cuoco did not make that clear.

The FBI has since said it is aware of the situation and "addressing" the hack.
