Chivalry is not dead, after all. Parks and Recreation
's Chris Pratt, who got engaged
to actress Anna Faris late last year, knew she was The One immediately.
"I knew I wanted to marry her pretty soon [after I met her,]" he told PEOPLE Thursday at the premiere for his new NBC series. "It took a while for me to admit it, because it would be crazy to be like, 'I want to marry you' the first day I met her. But I could have!"
Pratt, 29, also explained that although he's wearing a wedding band already, the couple have yet to tie the knot. "I just kind of wanted one," he said. "She got one and I was like, 'I want one!' "
With Faris, 32, on hand to watch the series' premiere live at Hollywood club MyHouse, Pratt said they plan to wed this summer. "We're going to defy convention and not plan anything big," he said. "We're just going to go on vacation and come back married."
In the meantime, Pratt is enjoying filming Parks and Recreation
with cast members Amy Poehler, Rashida Jones and Aziz Ansari. "It's the most fun work I've ever done," he says. "It's a hilarious cast."
