Superstar pop singer Britney Spears has a private jet in the vicinity of her home in Los Angeles so she can head to Mississippi as soon as possible and be present at a local hospital when her 17-year-old sister Jamie Lynn gives birth to her first baby, China Daily reported.

Britney and her father Jamie are going to be “standing by” to receive the phone call which will announce them that Jamie Lynn is going into labour and off they go with the private jet.  

However, Britney – mother of two children with Kevin Federline – won’t be in the delivery room when Jamie Lynn gives birth, she has been very supportive so far. The singer has been in constant contact with Jamie Lynn and gave her advice when she needed it.

According to a source close to Spears, the singer has been very close to her little sister after she went to Jamie Lynn's baby shower. Actually, Britney flew to see her sister yesterday to support her because she allegedly had some health problems.

Jamie Lynn and her 19-year-old fiancé Casey Aldridge are expecting a girl. The speculation has been made after the “Zoey 101” actress has been seen loading a pink baby carrier into her car. The two lovebirds have moved into their new $300,000 home in Liberty, Mississippi.
