Jamie Lynn Spears Tweets birthday photo of Maddie Brean

It’s hard to believe but Britney Spear’s little sister,  Jamie Lynn Spears, is celebrating her big 2-0 birthday today, Monday (Apr. 4)

Seems like just the other day, Jamie Lynn was pregnant with her out-of-wedlock daughter, who is now an adorable 2 1/2. And Jamie Lynn certainly was a trend-setter.

Why, she paved the way for then-vice presidential candidate Sarah Palin‘s daughter Bristol Palin got pregnant by Levi Johnston and later became an ambassador for abstinence and appeared on Dancing with the Stars. How time flies. Jamie has stayed under the radar for the past two years.

“What else do you do on your 20th birthday weekend?” she tweeted Saturday when posting this cute pix of hugging her toddler Maddie Brean.

Later the same day, Jamie wrote, “Just grilling for Maddie B,” and posted a photo of herself holding tongs and a potholder in front of a barbecue grill. Sweet.

Congratulations, Jamie Lynn. Looks like you have a beautiful baby and a perfect life.
