During the conversation, Jamie Lynn also called Britney a “good big sister,” adding, “I love her. Me and her throw down. The world’s seen that. I’ve learned to stop talking about it publicly, but you know what, family’s fight. Listen, we just do it better than most.”As Thompson, 31, noted that “everyone’s got stuff they argue about all the time,” Jamie Lynn replied, “Me and her both have had a very complicated upbringing.““We’ve had very complicated circumstances and we both had to deal with them in different ways. Sometimes we took it out on each other when perhaps we shouldn’t have,” she continued. “… I’ve been the one person in her life — and she can say this — I’ve never taken anything from her, you know? I’ve been the one person in her life who’s always said, ‘I just want to be your sister.' "
Added Jamie Lynn: “We just had a really weird life so we can’t explain it to many people, but at the end of the road I know that that’s my family, I love them.”

Jamie Lynn then spoke about looking up to her sister from a young age. “Anything my sister did I always thought was the best,” she said. “When it came to my sister, even if I felt anything, if anyone said anything I was ready to go. I was like, ‘Don’t talk about my sister, she’s the best.’ "
