Pop star Britney Spears left her sister Jamie Lynn's side as she was giving birth because she got tearful and it made her miss her own sons.

Spears was seen wandering the hospital and was not spending time with her 17-year-old sister and her new born Maddie. Spears was seen crying even at the airport back to Los Angeles.

Spears' estranged husband Kevin Federline has custody of their two sons. But the singer was recently granted overnight visiting rights during a custody hearing. She is happy with the direction her life is taking and she could have even more access rights at the next hearing on July 15.
