"Christmas Eve the love of my life surprised me on his knees asking me to be his forever," wrote Garrn on Instagram. "He changed my life the day we met and showed me what love really is—so yes I cannot wait to spend every day (well almost) of my life with you." The photo depicts the newly-engaged couple sharing a kiss while Garrn shows off her new accessory. The three-stone engagement ring features an emerald-cut diamond flanked by two smaller diamonds all set on a gold band.
Pettyfer also announced the news on his own Instagram account, sharing a boomerang of the couple kissing. "Some people marry their best friend. Some people marry their soulmate. I got both," he captioned the post.
The couple got engaged after just ten months of dating. This marks Pettfyer's third engagement, who was previously engaged to Elvis Presley's granddaughter Riley Keough and Dutch model Marloes Horst. From 2013 to 2014, Garrn dated actor Leonardo DiCaprio.
