Being Britney Spears' cousin & pal, means answering some questions!
That's what Alli Sims will be doing soon!
Sims was served with legal papers yesterday ... concerning the ongoing custody battle between Spears and Kevin Federline.
Sims will have to testify about Spears's parenting skills! Oh ... Oh!
Britney & Alli were together partying yesterday, when Alli was approached by a guy from IMS-Security ... Alli was shocked, she covered her face and said 'Oh my God!'

Sims recently commented on the issue of Britney Spears' parenting, she said: "Britney is a wonderful mom and she is so hands-on ... Britney loves those babies to death. And they adore her."

Well, she's going to be under oath ... so, she's going to have to be totally honest about it! Will her answers be just the same?
