Reed, 26, and Somerhalder, 35, were first linked in July after they were photographed together at the Farmers' Market in Los Angeles.

"[Nikki and Ian are] smitten with each other and love spending time together," a source told E! News at the time.

Reed’s latest romance comes just a few months after she filed for divorce from American Idol alum Paul McDonald. The former couple was married for two years.

"After much consideration, Nikki Reed and Paul McDonald are ending their marriage. They have been living separately for the past six months due to work obligations," the actress' rep said in a statement"They will continue to share their love of music, and are still working on their debut album, I'm Not Falling, releasing in 2014. They remain best friends and look forward to their continued journey together."

Somerhalder was also in a long-term relationship with his Vampire Diaries co-star Nina Dobrev for almost three years before they split last May.
