Nikki Reed and Ian Somerhalder are engaged, according to reports out Thursday.
The "Twilight" actress and singer and the "Vampire Diaries" actor were "crazy happy from the start," a source told E! News.
A source told Us Weekly that Reed "accepted with glee" when Somerhalder popped the question.
The twosome, whose couplehood started making headlines in July, already co-parent several critters and have been vocal about their animal advocacy. They've also started a production company together, according to Gossip Cop.
On Sunday, they attended the InStyle and Warner Bros. Golden Globe Awards after-party as a couple.
"I love how diverse you are as a human being and and artist," Somerhalder, 36, posted to Instagram in November, when Reed released the song "Fly With You." A portion of proceeds from the recording goes to an animal charity, Wildlife Waystation.
Reed, 26, was previously married to Paul Anderson of "American Idol" fame. The met in March 2011 and married seven months later, or maybe only four months later, then announced their amicable split in March 2014. She filed for divorce last May.
Somerhalder previously dated his "Vampire Diaries" costar Nina Dobrev for about three years. They broke up in May 2013.
A rep for Reed did not respond immediately to a request for confirmation and comment.
