Justin Long and Amanda Seyfried may have taken the next step ahead in their relationship as the two actors were spotted enjoying a romantic dinner date in West Hollywood, Thursday night.

Amanda Seyfried may be breaking millions of hearts but the adorable "Lovelace" actress and Justin Long make the perfect match. Both two actors have been spotted one too many times together and seem to be well-connected with each other . According to US Weekly, Seyfried and Long have been spending some quality time by "hanging out more," and "going on date-like activities."

Despite their busy schedules, the reportedly-in-love couple are making time for each other and are just waiting to see "where it goes," a source exclusively revealed to US Weekly.

During the premier of Seyfried's new film "Lovelace" in New York, July 30, Long accompanied the former child actress.

"Justin came alone and stayed close to Amanda all night," another source told the magazine. "They weren't making out or anything like that, but they were just inseparable during the event. He hung out when she talked with others."

The "iSteve" actor could not stop complimenting Seyfried on her work in "Lovelace" and he wrote on Twitter with a touch of humord, of course.

"Adjectives don't do justice to @AmandaSeyfried's fearless + transformative perf in #Lovelace (though I would've been better) -just go see it," the 35-year-old actor tweeted Sunday.

Most recently, an eyewitness spotted  Seyfried and Long enjoying dinner at Cecconi's, an Italian restaurant in West Hollywood. A report in E! News said that the new-couple talked the "entire time" at dinner as they sipped through glasses of white wine.

Seyfried was recently linked to "Dexter" actor Desmond Harington. She shared a long three year relationship with British actor Dominic Coope before they broke up in 2010.

Long shared a relationship with Drew Barrymore, whom he dated for three years before they split in 2010. The "A Case of You" actor was also linked with Kate Mara, and reportedly celebrated his 34th birthday with the "House of Cards" actress.
