Vampire Diaries actor Ian is said to have popped the question to Twilight actress Nikki after six months of dating.
While the happy couple haven't confirmed the news themselves, multiple sources have said they're absolutely thrilled to be planning a future together.
An insider told E! News: "They're so happy. They were crazy happy from the start. Their families love each other. It just feels really right."
Ian and Nikki were friends before they began dating last year, and took their romance public in July 2014.
It will be the first marriage for Ian and second for Nikki.
She was previously wed to American Idol contestant Paul McDonald. She memorably met the singer-songwriter on camera, after he was introduced to her at an LA premiere in a meeting recorded for the show.
They announced their split in March 2014, but revealed they'd actually been separated for the previous six months. She filed for divorce in May that year.
Ian, meanwhile, was previously in a long-term relationship with his Vampire Diaries co-star Nina Dobrev.
