This real life relationship began as an onscreen romance on a popular book turned TV series. And while their love has fizzled on the show, the actors' passion shows no sign of stopping.
The couple was recently caught taking a stroll in New York City's Meatpacking District and from the looks of things this guy couldn't help but get a little squeeze of his hot blonde girlfriend.
Think you know which celeb couple was caught engaging in a little sidewalk PDA?
It's Gossip Girl stars Blake Lively and Penn Badgley! These two make such a cute couple in real life—it's about time GG brought back their onscreen relationship, right?! Are there any Serena and Dan fans out there who feel the same way?
