While many folks enjoyed a sunny weekend day, Sara Bareilles spent her Saturday pondering and tweeting. The 'Uncharted' singer had a few questions for Lady Gaga about where she keeps her "disco stick." Meanwhile, poor Trey Songz sent tweets to his fans in hopes that they could help him find a specific pretty lady that he met on a flight. Back on the ground, both Mike Posner and Colbie Caillat had issues with the Saturday traffic, and Bruno Mars filled the Twitter world with tweets about annoying songs that get stuck in your head.
