Amanda Seyfried, Boyfriend Justin Long Engaged? 'Dear John' Actress Wears Huge Bling As She Knits Her Way Through NYC

Amanda Seyfried and boyfriend Justin Long are rumored to be engaged after the "Dear John" actress was spotted with a huge bling while walking her dog and knitting her way through New York on Monday.

The Radar Online posted a photo of what it described as a "giant diamond ring" that the "Lovelace" actress wore, which the tabloid took to mean that Amanda Seyfried and boyfriend Justin Long are engaged.

The actress was dressed down for the day as she wore skinny jeans, a v-neck top and navy pilot jacket with fur collar. She also pulled back her long blond hair and completed the look with dark glasses.

"Did her boyfriend Justin Long propose? While her rep didn't respond to RadarOnline.com's request for comment, a rock that big seems to symbolize more than an early stocking stuffer for the blonde beauty," it said.

Amanda Seyfried will next be seen in "Ted 2" to play John's girlfriend, who will be at odds with his relationship with Ted.

Meanwhile, MailOnline noted how Amanda Seyfried was multi-tasking while walking her dog in NYC.

It said this ability to multi-task has helped her get worldwide recognition through movies such as "Mamma Mia!" and "Les Miserables."

"The beauty was accompanied by her beloved Australian shepherd Finn, who wore a brown bandanna on their trip to what appeared to be a dog park," the publication said.

Amanda Seyfried just reunited with her dog, Finn, just last week after leaving for Paris with her mother. She immediately took to social media to share the reunion which she captioned: "I thank Finn for giving me some heavy life lessons. You don't need words! #Finnsight."

According to RadarOnline, if Amanda Seyfried and boyfriend Justin Long are indeed engaged, they "would have plenty of company, as studies indicate more than 40 percent of couples get engaged between November and January."
