As you might know, the princess of pop celebrated her 30th birthday on the 2th of December! However rather than throwing an extravagant party, she spent her birthday in a calm, homely manner! She started off by watching and responding to her her celebrity friends' and fans' videos and text messages in bed with her sons Preston and Jayden and then later headed out to a privately rented ice-skating rink in Houston with her boyfriend Jason Trawick! She then rounded the day off with a family dinner. How cozy and responsible!
