Britney Spears' 22-year-old sister channels her inner country girl in the new vid, which features the former Zoey 101 star singing intimately in a recording studio.
"Lying in the green grass underneath the blue sky," Jamie Lynn sings. "Looking at a good man, you oughta be the right guy/that's got the kind of heart that any girl would die for/so how could I want more? How could I want more?"
"Treats me like a princess, let's me have it my way," she croons. "I could tell he's hanging on every word that I say/all he does is love me, he swears that's what he's here for/so how could I want more? How could I want more?"
Ryan Seacrest premiered Jamie Lynn's video this morning. He tweeted, "PREMIERE: @JamieLynnSpears embraces her country roots in "How Could I Want More" video!"
Britney also tweeted her excitement for the video earlier today, writing, "Can't believe how beautiful my sister looks in her #HowCouldIWantMore video. OMG! Watch on @OnAirWithRyan."
Last week, Jamie Lynn opened up to E! News exclusively about her promising music career. "I don't think you just wake up one morning and decide you're going to sing. It's something I've always done," she admitted. "But as a young child, like I said, all that was offered to me. You don't know how to say, like, 'Oh, this is what I want for the rest of my life.' You can't make those kind of decisions at 10 years old."
"It's seeing it all here and it's real," she continued. "It's like, 'Oh my goodness, I'm really gonna do this.' It's like my second baby."
