Jennifer Aniston Engaged: Insiders Hope She 'Has Finally Found Mr. Right'

Now that it has been confirmed that Jennifer Aniston is engaged to actor Justin Theroux, is it possible for her to finally get off the "Pitt-y" train people put her on seven years ago, when then-husband Brad Pitt left her for Angelina Jolie?

"The weekly magazines have followed every step of her relationship with Vince Vaughn, model Paul Sculfor, John Mayer, Jason Sudeikis and Bradley Cooper," celebrity journalist Marianne Garvey, who appears on Oxygen's "Girlfriend Confidential: NY," told me. "All of those relationships ended in disaster. Hopefully Jen has finally found Mr. Right, but until she finally says 'I do,' it's going to be a hard train to get off."

Jennifer has said that the biggest misconception about her is that she's unhappy, which she insists is not the case. Hopefully fans will now believe her.

"Look, she got dumped by one of the most beautiful people in the world for the other most beautiful person in the world. How can you not feel sorry for her?" says Amy Rosenblum, who runs media training company Media Masters. "Until we see her glowing in her wedding dress on her wedding day, we will always worry about Jen. We literally see her as our favorite friend."
