Jon Hamm & Jennifer Westfeldt
After 14 years together, the romance is still going strong for the hunky Mad Men star and his girlfriend. Swoon.
Sienna Miller & Tom Sturridge
The London lovebirds stop in the middle of the streets for a sweet display of affection. Hey, it's a good enough reason as any!
Jessica Simpson & Eric Johnson
Somebody gets a fat birthday kiss on her big 3-0! Yep, Jess brought along her fiancé on a vacation to Capri, where there was plenty of lovin' going on.
Miley Cyrus & Liam Hemsworth
Although this embrace was on the set of their flick Last Song, it's easy to see how their onscreen chemistry would easily transfer offscreen, too.
Will Smith & Jada Pinkett Smith
While planting a pucker on her superstar hubby, the actress throws in a little added affection for good measure.
Matthew McConaughey & Camila Alves
Let's face it. It can't be that hard to feel frisky when your sexy significant other is almost always shirtless. Of course, having a smokin' hot bod yourself probably doesn't hurt either.
Jake Gyllenhaal & Reese Witherspoon
Sure, they may be at a basketball game, but that doesn't stop the cute couple from playing a game of tonsil hockey.
Justin Timberlake & Jessica Biel
These two lovebirds would be the perfect choice if they ever decide to revive the old Big Red gum "kiss a little longer" campaign.
