But it looks like she's finally undergone the full makeover people anticipated since she first shocked the show's judges and audience with her unexpected singing abilities!
Just goes to prove, you can't judge a book by its cover, nor a Boyle by her brow.
Boyle has been out of the public eye since finishing a disappointing second on BGT, which prompted her to check into a mental health clinic.
Her health -- and career future -- were uncertain until she gave her first interview this morning on the "TODAY" show looking fabulous.
Back in April, Boyle took the first step with what appeared to be an eyebrow wax. But now, she's gone even further and dyed those newly groomed brows (and her formerly salt and pepper hair) a warm, flattering brown.
She also has defined her eyes with shadow and liner, perked up her cheeks with some blush and colored her lips a bright berry shade.
And of course, the crowning glory is her new 'do -- a short layered crop and smooth blowout (quite a change from those overly poufy curls).
Susan, we approve!
