Britney Spears is going to be pissed!! A source for PageSix.com says Brit's ex, Kevin Federline, knew about ex sister-in-law, Jamie Lynn Spears's, pregnancy on Monday. As of Tuesday night, Britney was still in the dark about the latest family drama. "Kevin knew before Britney that Jamie Lynn is pregnant," a K-fed "family insider" said. "In fact, Britney's mom, Lynne, told Kevin about it on Monday, because Lynne wanted Kevin to be prepared when Britney found out."
Oooooh. Not going to go over well with the Britster. "We're waiting for the fallout from Britney," the insider added. "Kevin is sure Britney will flip out and blame her mom and dad." Can't wait!
