Anne Hathaway has proudly displayed her new engagement ring during a romantic stroll with new fianc Adam Shulman.

The 29-year-old actress was very public with her affection for her man as she kissed him during a love fest in a Brooklyn park over the weekend.

She looked ecstatic as she flashed her four-carat cushion cut diamond sparkler which was co-designed by Kwiat Heritage Jewels and Adam himself.

"Adam he did work with us to design a ring that he knew Anne would love," owner Greg Kwiat told People magazine adding that the diamonds are certified conflict-free."

"He had a very strong vision for what he knew Anne would love."

The betrothed couple walked through Fort Greene Park with Anne's chocolate Labrador, Esmeralda and at one point stopped and sat under a tree where the Rachel Getting Married star rested back on Adam and laid her head on his chest.

The loyal dog has been through a lot with Anne as she used to share Esmeralda with her ex-boyfriend Raffaello Follieri, who is currently in prison serving a four-and-a-half year sentence for illegal financial dealings.

Anne had dumped the Italian businessman back in June 2008 after she found out that he had taken over $3.6 million from investment funds and real estate firms, partially to fund the lavish lifestyle and expensive gifts he bought for the starlet.
