Alli Simpson Goes Mindless for Her 14th Birthday!

Cody Simpson may be big in the spotlight right now, but yesterday his younger sister Alli got her chance to shine for her 14th birthday!

Alli Simpson started her birthday not in the best of ways, as she tweeted “i just woke up and it's my birthday..first thing i do? step in my dogs pee. awesome way to start the day! -__- haahahhaa”  Her luck quickly turned around, though.  Later, Alli celebrated turning the big one-four at Radio Disney where she was serenaded by the one and only Mindless Behavior who gave her a funny, but thoughtful version of “Happy Birthday!”  You can check out the video below.

Want to get info on all things Alli?  You can check out her website at AlliSimpson.com.  There you can learn about what she did in Australia before making the big move out to the states (she was a big swimmer!)  Learn about what fashions she’s into, and see what Alli has in the works for her fans.

We want to wish Alli a happy belated birthday, hope it was everything you were hoping for, girl!
