Michelle Trachtenberg is single no more. The movie beauty reportedly has found a new love in Brandon Hirsch, a 26-years-old manager at New York City hot spot Butter.

Trachtenberg and Hirsch first stepped out as a couple on Friday night June 1st at The Killers concert at the Hard Rock Hotel, during which they were spotted kissing before then headed to Caesars' Palace's Pure Nightclub, dancing to tunes spun by DJ AM.

The next day the in love couple was spotted "making out all night" at the Venetian's Tao Nightclub for the Oceanaut Watch party.

A source close to the actress told People, Trachtenberg and Hirsch first met two years ago, but got reacquainted about six months ago and have been quietly dating. The source, moreover, also revealed that despite her staying in LA, Trachtenberg is "becoming bicoastal and spending a lot more time in New York to be with him. She wants to be really low-key about the relationship since this is the first time she's dated someone who is not in the business."

Trachtenberg previously dated Canadian actor Shawn Ashmore from 2004 to December 2006 and had been romantically linked to former "Sex and the City" actor Jason Lewis.
