Britney Spears' pal Alli Sims was served with legal papers at 2:30 a.m. Sunday forcing her to testify about the singer's parenting skills.
Sims was leaving a party when Aaron Cohen of IMS-Security handed her a deposition subpoena from Mark Vincent Kaplan, lawyer for Spears' ex-husband Kevin Federline.
Federline filed for primary custody of Sean Preston and Jayden James last Wednesday. He is apparently worried about Spears' behavior and believes she is exposing their sons to "unnecessary risks."
Sims recently told People magazine that Britney is "a wonderful mom and she is so hands-on. ... Britney loves those babies to death. And they adore her."
Spears was also at the party with Sims, but apparently did not witness the serving of the papers.
