Jamie Lynn Spears Britney Can Talk S*** All She Likes ... Just Happy She's Breathing
Jamie Lynn Spears isn't sweating her sister's nasty comments about her ... with people close to her revealing she's developed a positive way to look at Britney's trash talk.
Sources with direct knowledge tell TMZ ... Jamie Lynn's only worried about Britney's well-being, so she's actually fine with all the smack Britney fires off on social media -- because every comment is a sign Brit's still alive.
This revelation about Jamie Lynn's outlook comes on the heels of Britney repeatedly calling her a "little bitch" and a "little s***" in a rambling, barely coherent video she posted, then deleted from Instagram.
