Britney Spears celebrated her 27th birthday on Dec. 2. On the public level, Spears celebrated on a TV show. Everyone was reminded it was Spears’ birthday on “Good Morning America.” In her own private time, Spears dressed up in this saucy, low cut black gown and enjoyed teasing those around her with little peekaboos. I’m not sure how this dress was approved by her personal censors but yay! We got to see some cheeky pictures here.
