So you Googled and Googled and Googled until you found a girl with a quite common first name and a relatively common last name, who is a brunette, and you've decided that it's her, despite a total lack of contextual evidence?
And you explain the fact that the resemblance is, at best, vague by saying she's had plastic surgery?
Hey did you hear, Bill Nye The Science Guy is Daniel Tosh's dad. Because they look alike.
And even if this was true, who are you to judge her or indict her even for lying about her age? What is the difference between a stage name (which countless performers have) and a stage age? She has a right to a reinvention of her past, and of her persona. It's not for you to question or comment on, at least certainly not in with spiteful, seething jealousy-spin that propels your every fart on this site.
Deal with it: whether she's 39 now or 49, she'll look better at 99, or even as a corpse, then you did in your prime. She's been touring the world with one of her musical heroes for almost a decade now, has not had to have a "real job" for ages, has just finished recording an album with Dave f***ing Grohl, has had Bowie sing on an album that she made before she even met Morrissey or became famous, and...even if she and Morrissey were on opposite ends of the earth, she'd still have an emotional/personal proximity to him that you with all your myriad signs and dreams and wet granny-panty grossness could never hope to have.
You are the very definition of loser. Get the f*** over it, get a life, get a f***ing job you utter f***ing turd.
