Mila Kunis is making the latenight talk show rounds to promote "Jupiter Ascending." But when she showed up on "Conan" last night, the conversation derailed pretty quickly into a discussion of, um, other planets.

Specifically, the ones attached to Mila's chest.

"Boy, do these things grow," the actress said. "I don't know how to deal with them, because I've never had them, and so I've always dressed for a flat-chested girl -- and now I'm busty, I'm like, 'Whoa, check it out!'"

Needless to say, everyone in Conan's audience (and the host himself) took her up on the invitation, and checked. (It would have been rude not to!) And while we love Mila for many, many reasons that have nothing to do with her spectacular new rack, not gonna lie, they're pretty amazing.

Looks like Channing Tatum agrees, too.
