The 28-year-old former child star says her much-younger boyfriend lives in California and works at a bait shop, reported Ace Showbiz.
"I am very needy for friendship and I hate men. But I can now say I'm engaged - get away from me. I want to be married and I want to be away from people," Bynes was quoted as saying In Touch magazine.
After getting married, the 'Easy A' star plans to live in New York, saying," I really like walking and riding my bike, and in California, you need to drive. I really do not enjoy driving. I don't like the way I look in a car. The lighting is very bad."
"I want boys, for sure. However many I can pop out. I don't want a gorgeous girl around. Then I would feel way jealous. Ew," Bynes said.
The actress has not decided the date, but she said the nuptials would take place at the London hotel in LA.
Bynes, who made headlines for her bizarre behaviour last year, was most recently seen enjoying a bike ride in New York.
