The final moments of Taylor Swift's 'Blank Space' video and Britney Spears' 'Toxic' vid end with the superstars seemingly killing their men -- and giving them one last seductive kiss goodbye. Whose "killer kiss" do you like better?

By all accounts, Taylor Swift goes a little cray in her 'Blank Space' music video -- and we can't get enough of it. Forget "drunk on jealously," Taylor goes full-on psycho, knocking out her unfaithful man and tearing everything of he owns to shreds. But regardless of the fact that he's unconscious, Taylor still bites his lip in the most shockingly seductive manner. Talk about the kiss of death!

Britney Spears' 'Toxic' vid ends with flight attendant Britney making out with her super hot  hunk -- before quickly poisoning him with a glowing green liquid. (You know, the usual.) Of course, Britney's seductive moves are so irresistible that they're even worth dying for. But don't worry, before giving her guy the final kiss-off, she also closes his eyes after his death. So respectful.
