Although she can’t be very far along, Kristen Bell ‘s newest baby bump made its stage debut, albeit hidden by clothing, last night in Hollywood for a very special performance of the hippy hit musical HAIR. Between last year’s Disney fairytale Frozen and the criminally underrated Reefer Madness, Ms. Bell has a set of pipes that audiences can experience first hand all weekend long at the Hollywood Bowl. Kristen and her husband Dax Shepard are currently expecting their second child together. When the baby arrives, he or she will play younger sibling to the pairs 15-month-old daughter Lincoln.
