Lip-Lock Knock-Out: One Direction's Done, So Vote Now To Save Your Favorites

Learn which songs made it to Round 4 in the quest to find the ultimate love song.

Is it getting hot in here? Or is it just our Lip-Lock Knock-Out tournament?

We're now in Round 4 in the battle to find the ultimate love song, and there's only four songs left to duke it out.

Ciara's "Body Party" didn't give Selena Gomez's "Come & Get It" a chance, moving on to Wednesday's (February 19) match-up with Ariana Grande's "The Way," which put One Direction's "Kiss You" in a tumultuous frenzy to hold on before eventually beating it out.

On the other side of the bracket, Smilers will be happy to hear that Miley Cyrus' "Wrecking Ball" swung through at the last second to knock out Fifth Harmony's "Miss Movin' On." And although Bruno Mars had the lead for a second or two with "When I Was Your Man," Pink's "Just Give Me A Reason" stayed strong, sprinting to victory.
