heatworld can’t quite believe this, but Kevin Federline was reportedly told about Jamie Lynne Spears’ pregnancy – even before Britney! "Kevin knew before Britney that Jamie Lynn was pregnant," a Federline family insider told the New York Post. "In fact, Britney's mom Lynne told Kevin about it on Monday because Lynne wanted Kevin to be prepared," they said. Kevin is thought to provide Britney’s parents with their only access to their grandsons, after their troubled daughter shut them out of her life months ago. And now Britney seems to be completely out of the loop. She even reportedly told a news agency earlier today, as the news of Jamie's pregnancy was breaking, “My sister is NOT pregnant!” The confirmation from the Spears family is sure to leave Britney fuming. The insider continued, "We're waiting for the fallout from Britney. Kevin is sure Britney will flip out and blame her mom and dad."
