At the end of August, Glee star Dianna dyed her barnet platinum before chopping the lengths into a jaw-grazing crop.
But while attending the Extremely Piaget launch party yesterday evening, Dianna flaunted a much longer pale blonde bonce...
Either her hair grows VERY fast (in which case, we're mega-jealous...), or she clipped in a few sneaky hair extensions!
Dianna's new mane fell just below her collarbones, and she styled her fresh strands in a side parting while tonging the lengths into soft, retro curls.
But aside from her fab new 'do, Dianna packed a punch on the fashion front too while sporting an adorable periwinkle blue frock complete with a flared, 1950s-style skirt and cute flower embellishment near the neckline.
The starlet paired her fancy frock with strappy electric blue heels and a statement beaded clutch, finishing her look with a classy jet black mani and pretty petal pink lips.
No matter what hair length Dianna rocks, she always looks gorgeous, don't cha think?!
