Entertainment Tonight reported Thursday that the 32-year-old actor and "Twilight" star proposed to Juce TV host Brittany Gonzales 11 months ago after a year of dating.
Gonzales was spotted wearing her engagement ring during an outing with Lutz Thursday in New York, according to Us Weekly. The couple were overheard discussing their wedding plans with a friend.
"A woman sitting outside having breakfast shouted Kellan's name and he walked over to her with Brittany. She was congratulating them and asked them if they were getting married in New York or L.A.," an onlooker said.
"They walked into the restaurant and when Brittany opened the door I could see her large engagement ring," the source added.
Lutz and Gonzales have largely kept their relationship quiet, but occasionally gush about each other on social media.
Gonzales penned a sweet message to Lutz in an Instagram post Sept. 8.
"When your reality is better than your dreams ever were," she wrote.
