Between Blake Lively's kangaroo selfies with Taylor Swift and her hilarious tendency to shut down rumors, she's been owning the Instagram game lately. To ensure that her reign as queen of social media is a long one, Blake posted a supercute Throwback Thursday photo of herself cuddling with 90210 actor Jason Priestley. She captioned the snap, "#tbt to when Serena Van Der Woodsen and Brandon Walsh were a thing. (Shh don't tell @robynlively0)." In addition to making everyone on earth "aww!" uncontrollably over baby Blake, it's probably inspiring so many 90210/Gossip Girl fan fiction ideas. See the adorable picture below, and check out her colorful outing in Brooklyn!
