Amanda Seyfried and boyfriend Justin Long are getting serious. The "Lovelace" star, 27, showed off her legs in short shorts while walking with her beau, 35, and dog, Finn in New York City on Wednesday morning.

Seyfried stepped out in Daisy Duke-style denim shorts, blue polka-dotted blouse and dark sunglasses. Her beau kept it more casual in a light-blue printed t-shirt, jeans and dark shades.

Their adorable dog was even dressed up with a green scarf around his neck, reported the British newspaper.

The twosome are getting very close. Though Long is known for keeping his romantic relationships private, the actor didn't mind indulging in some PDA with Seyfried and Finn this week.

According to PopSugar, Long shared a romantic day with Seyfried, with the two kissing, cuddling and holding hands at a NYC park on Wednesday.

After the twosome checked into a hotel together, they didn't wait long to enjoy the city and each other's company. Long even gave a smooch to Finn when the couple arrived at a city airport earlier this week.

US Weekly had reported that the couple were taken their friendship to the next level last month. They have been inseparable ever since news broke about their romance.

"I'm not positive how they exactly met, but they've known each other for a while, when they were seeing other people," a source told US. "They recently started hanging out more, going on date-like activities. They're both busy...but they're seeing where it goes."
