OK! magazine has reported on some Miley Cyrus engagement rumors. According to the story Miley was "Talking about a wedding as soon as she turns 18 [in November]. She’s even asked her mom if she can wear her wedding dress."
Apparently the rumors are completely bogus. Miley was likely joking when she was asking about the wedding dress. Miley's parents don't want her to rush into marriage, and a source close to Miley laughed off the story.
