Jennifer Aniston is showing no shock or sadness about her shocking breakup with boyfriend John Mayer. She was seen taking a casual walk around New York happily posing for the lens.

A source says,” It’s like Jen is on nothing less than a revenge tour. In the past, Jen shunned publicity and shrank from photographers’ lenses, now she’s openly encouraging the attention, smiling, showing off her body, and creating photo ops!”

John after splitting with Jen revealed that he wanted to “be alone”.

He said, “There’s no lying, there’s no cheating, there’s no nothing. People are different, people have different chemistry. I ended a relationship to be alone, because I don’t want to waste somebody’s time if something’s not right.”

Jen spent a nice time with her Object of My Affection co-star, Paul Rudd, at Mayer’s favorite dining place, Nobu.

An onlooker said, “Jen was glowing, smiling and being very friendly as she ate tuna tartare, rock shrimp and spinach salad with a glass of wine. It was hard to believe this was a woman who just broke up with her boyfriend.”

Friends of Jen insisted that she never saw her future in Mayer, adding, “She didn’t see herself and John having much in common or having a future together.

“She wasn’t fazed by the ending of it. She wasn’t hurt at all. She feels fine.”

Well it’s good for her.
