It’s Twilight star BooBoo Stewart’s birthday today! BooBoo turns the big 1-7! Woo hoo! We would say we hope he has a fun celebration, but we know he already has! According to Cambio, BooBoo’s sister, Fivel, threw him an awesome surprise birthday party where they ate his favorite Cold Stone Creamery ice cream cake â€” Mint Chip! Sounds like our kind of party.
