Baby news, NASCAR news and a country star recovering from surgery -- it's all included in this week's list of top tweets. Lauren Alaina and Brad Paisley both found themselves dabbling unusual collaborations, and it sounds like the 'American Idol' runner-up's next project could be on a rock n' roll album.

'The Voice' contestant Gwen Sebastian also makes the week's top tweets with a joke at the expense of her coach Blake Shelton. Also look for tweets from Taylor Swift, Kellie Pickler and Martina McBride, who finally figured out what that "glowy thing" is all about.
