pretty little liars a bite me the originals 'Pretty Little Liars' 'A' responds to 'The Originals' ad: Feud alert?Is there a feud starting Tuesday nights at 8 p.m.?

New CW drama “The Originals” launched a pre-emptive strike Tuesday (Jan. 14), as it was revealed that the show is airing a commercial on ABC Family during “Pretty Little Liars” that tells viewers who are sick of “A” and his/her antics to change the channel to “The Originals.”

“PLL’s” resident villain “A” has responded with the above photo featuring one of its patented “A” messages: “Bite me, #LiarsUnite, #UnOriginal.”

Get it? Because “The Originals” is about vampires?

The next 10 weeks will mark the first time the two young adult dramas will air head-to-head for any length of time. They previously shared one common airing during “Pretty Little Liars” 2013 Halloween episode, which saw “PLL” beat the vampire drama by almost a million viewers.

Which show will you be watching tonight at 8 p.m. ET/PT?
