"He's going to be my husband," she giggled to E! Online at the I Heart Ronson for JCPenney party in LA.
And though she and the baseball player and former "The Hills" star have seemingly had a whirlwind romance, the celebutante said that Doug's been part of her life for quite some time.
"We're best friends," Paris said. "It's not like we just met. We've known each other over the past year. I was in a relationship before and we reconnected. I'm really in love and really happy."
But according to Doug, the couple doesn't have wedding bells in mind just yet.
"You never know," Doug said.
Until then, he's got a place on the set of the second season of Paris' "My New BFF," where she said he comes up with "funny ideas."
"It's good having my boyfriend on set and watching," she said, adding that things didn't work out with Season One winner Brittany Flickinger. "I want a best friend who wants to be friends with me because I'm a good person and a good friend, not for any other reason. I've been fooled by so many girls."
