With Britney, 34, and brother Bryan, 39, Jamie Lynn tells PEOPLE she sometimes felt like she had “two sets of parents.” To this day, the 25-year-old says, “we’re always giving each other advice.”
Jamie Lynn – seen here on the morning of her birth in 1991, with mom Lynne – says that entire Spears clan is close – and not afraid to face the music together. “If my family is going through something, we don’t try to pretend we’re perfect,” she explains. “To the public, that can look like we’re falling apart. But to us it’s just going through life.”
“I was a mouthy little thing,” Jamie Lynn tells PEOPLE. As for daughter Maddie? The 8-year-old “does takes after me,” the singer admits. “She’s very particular about certain things like I am.”
Jamie Lynn – whose new single “Sleepover” drops Friday – has always been performing. “As a young child, of course, I knew that I was creative and I was looking for creative outlets,” she tells PEOPLE.
Of Britney, who is in her third year of a Las Vegas residency, Jamie Lynn assures: “My sister is in a badass place right now.” And the pop icon motivates her own career: “It was inspiring to see what hard work and talent can do.”
“She’s been very motherly to me,” Jamie Lynn says of having a much older sister.
Having daughter Maddie as a teenager has helped Jamie Lynn evolve from the Nickelodeon star fans once knew. “When you have to be strong not only for yourself but for someone else, you grow a whole other layer of skin,” she tells PEOPLE.
Jamie Lynn, seen here playing around with Britney, says she regards her youth in Mississippi “fondly.” She elaborates, “All the experiences I got from my childhood are priceless.”
