Hollywood bombshell Megan Fox had gotten an engagement ring from on-again/off-again fiancé Brian Austin Green, but told "Extra" that she has no plans to walk down the aisle anytime soon!

"I'm not going to be married -- I'm not the marrying type," Fox admits to "Extra" on the set of her new film, adding, "and I know what your next question is going to be -- you're going to ask me, 'Why are you engaged if you're not the marrying type?'"

The sexy "Transformers" star explains, "I am impulsive and I love my boyfriend, but I have no plans of getting married any time soon."

Megan's next flick, "Jennifer's Body," slashes into theatres September 18.
