Britney Spears stopped at Starbucks on Friday before getting ready to head home to Kentwood with Sean Preston, Jayden James, and her father this weekend. Last night was big for Brit — singing on stage with Madonna, looking great, and risking the chance of running into Justin Timberlake who appeared later in the show. Apparently the exes saw each other at a rehearsal and said hi earlier in the day. While Britney and Justin are ancient history by now, we can't help but wonder what it was like for these former sweethearts to see each other again after all they've gone through. So tell us — are you curious what it was like for Britney and Justin to run into each other again?
