Britney Spears mocks Jamie Lynn | Sam Asghari finally unfollows her...

Britney Spears posted a video of herself twirling around in Mexico last night. 

She used it as an opportunity to take aim at her younger sister Jamie Lynn Spears. Her caption? ‘In Mexico now! When your sister says “I love her to DEATH”… you learn to start living!’ Jamie did an interview in January to promote her Fox show 'Special Forces: World’s Toughest Test,' and she said of Britney at the time, "I’m so proud of her, love her to death." Oh? So they're back to being estranged again?  As of yesterday, her ex-husband Sam Asghari no longer followed Britney on Instagram.
