Longtime couple Megan Park and Tyler Hilton, who met in 2006 on the movie Charlie Bartlett, are making it official.
The couple became engaged in California at the end of last year – with Hilton putting an extra-personal touch by proposing with his great-grandmother’s ring, they confirm exclusively to PEOPLE.
The two have not set a date for the wedding but hope to be married in California in the spring of 2015.
Park, best known for The Secret Life of the American Teenager, is currently filming the ABC show The Neighbors and will star in the movie The F Word, alongside Daniel Radcliffe, Adam Driver and Zoe Kazan. The film will be released later this year.
Hilton, known for his role on One Tree Hill, is working on a country music record in Nashville, due this summer.
