Jamie Lynn Spears says there's no rivalry between her and her 'Chillin' With You' duet partner Britney.
"Me and Brit, I'm sure no one believes me when I say, there is no rivalry!" she told Billboard. "You have to remember that we are 10 years apart, so I always saw her as a second mom. We have fun like only sisters can, but we don't have that young sibling rivalry."
That's nice to hear. Has she congratulated you on the success of your latest single though?
"She was one of the first people to call and tell me how proud she was of the success of ['How Could I Want More'], so charts won't come between me and her – never will!"
