Jamie Lynn Spears' 17-year-old daughter, Maddie, is just like Us - and loves singing along to Britney Spears' music. On Monday, December 15, Maddie shared a TikTok video of herself lip-synching to her aunt's 2000 song "Lucky." "She's so lucky / She's a star," she mimed. "But she cry, cry, cries in her lonely heart, thinking / If there's nothing missing in my life / Then why do these tears come at night?" Jamie Lynn, 34 - who is the sister of Britney, 44 - welcomed Maddie with ex Casey Aldridge. The Zoey 101 star also shares daughter Ivey, 7, with husband Jamie Watson.
