We're guessing Julianne Hough is REALLY missing her new hockey-playing beau Brooks Laich!
We've seen them holding hands, but the couple took their PDA to new, wet places when she swapped spit with him before dropping him off at LAX.
Gurlfriend must've forgotten the photogs AND thousands of other fliers were there…
…or maybe she just didn't give a f*ck! HA!
Awww, to be young and in lust!
