jamie lynn spears maddie Jamie Lynn Spears turns 20: Where has she been?When 16-year-old Jamie Lynn Spears announced her pregnancy in 2007, her career came to a screeching halt. Her Nickelodeon show, “Zoey 101,” wasn’t renewed, and Spears returned to her home in Mississippi to raise her child with then-boyfriend Casey Aldridge.

Spears celebrates her 20th birthday today, April 4 — and, no doubt, her first official day of no longer being a teen mom. “goodbye teens.. HELLO 20’s!!!” she tweeted, from her just-verified account. Spears mostly uses her Twitter to do what every mom does: share photos of her kid. Two and a half year old Maddie Briann Aldridge is adorable as ever. Let’s just keep her out of showbiz, please.

“What else do you do on your 20th bday weekend?” Spears mused, posting a photo of herself with Maddie, playing dress-up.

Well, we can think of lots of things, but… you go, girls.

If you don’t count all those paparazzi shots when she visits Britney, Jamie Lynn has stayed out of the spotlight — Whole Foods home videos notwithstanding — and by all accounts, she plans to remain a full-time mom for the time being.

We can’t help but wonder if there’s any chance of a career revival in her future, though.
