The United States can now call Dean McDermott one of its own!

Born in Toronto, Canada, the actor and reality star was officially sworn in as an American citizen along with 3000 others in downtown Los Angeles on Friday.

McDermott, 43, tells that the moment was "amazing....I was so proud and overwhelmed all at the same time. To take my oath and pledge allegiance beneath a giant American flag is something I will never forget. It was a very special and important day. To quote [singer] Lee Greenwood, 'I'm proud to be an American.'"

Adds his wife Tori Spelling, also on hand for the big day: "I'm so proud that I was able to be by Dean's side...He's wanted this for so long," she tells Us. "We stopped for lunch after at Taco Bell and he said 'This is my 1st taco as an American Citizen!' So cute!"

Home Sweet Hollywood stars McDermott and Spelling, 37, have been married for four years and have two kids: son Liam, 3, and daughter Stella, 2.
