This week's best TwitPics shine brightly, but perhaps the biggest gem from the bunch is the photo of Selena Gomez being crowned as an honorary player on the Ottawa Senators hockey team. Sel was given her very own jersey at the game in Canada on Thursday, just a few hours from Justin Bieber's hometown of Stratford, Ontario. Also among this week's TwitPics is an adorable shot of Hilary Duff that gives a peek into the future: a huge pumpkin belly! The singer/actress joked that her baby boy is growing by the minute, but she couldn't possibly look any happier. Elsewhere, Kelly Clarkson found herself sneaking down the CD aisles -- in disguise -- to buy her latest album, 'Stronger,' which hit shelves on Oct. 21.
