Jamie Lynn Spears Gets Haircut: Britney Spears' Little Sister Shows Off Sleek New Bob, Engagement Ring (PHOTO)

Love looks good on you, Jamie Lynn Spears!

Britney Spears' little sister took to Instagram recently to show off her new 'do -- a sleek new bob -- with the caption "#shorthairDontcare."

Maybe she's trying out a new hairstyle for her upcoming nuptials? The 21-year-old recently got engaged to boyfriend Jamie Watson, 30, showing off her brilliant round cut diamond to (who else?) her loyal legion of Twitter followers.

While it may seem like 21 is a little young to be getting hitched, it may just be a Spears thing -- big sis Britney famously married long-time friend Jason Alexander when she was just 22-years-old in Las Vegas in 2004, though she promptly got a quickie annulment.

Just five months later, however, Britney married backup dancer Kevin Federline (it's hard to believe it's been nine years already!)

Jamie Lynn may be doing things a bit backwards -- she already has a four-year-old daughter, Maddie Briann Aldridge, who she had when she was a teen -- but these Spears women certainly don't waste any time.

Or maybe it's a young Hollywood thing, since the "Zoey 101" star isn't the only young Disney actress getting hitched: 20-year-old Miley Cyrus is famously engaged to her (reportedly on-and-off-again) boyfriend Liam Hemsworth.
