Justin Bieber walked Selena Gomez out to her car in Toronto this morning. Selena spent time at his family's house yesterday as well, and it looks like she was rocking the same striped shirt today too. Selena's been in Canada with Justin all week, sharing park dates, grabbing lunch, and hanging out with Justin's hometown friends. The couple's trip north came after their PDA-filled getaway to Hawaii last week, and they may soon be on the go again. Justin's next stop is in LA, where he'll join MTV Movie Awards host Jason Sudeikis on stage. Selena's set to guest host the American Top 40 in Ryan Seacrest's place this weekend, which will double as a promotional stop for her upcoming film Monte Carlo.
