Glee star Amber Riley has been placed on bed rest after falling sick with a nasty bout of influenza. The actress/singer has cancelled a planned trip to the Essence Music Festival in New Orleans, Louisiana this weekend (06-07Jul13), and is resting up on doctors' orders. Riley is convinced she picked up the bug during a recent flight, and hopes to be back on her feet soon. In a series of posts on Twitter.com, she writes, "On bed rest for the next couple of days, gonna miss Essence Fest... but gonna receive some much needed rest... It's just the flu. Flying a lot always does this to me. Lots of liquids and rest and I will be good as new by the weekend!"
