Mimi’s been known to sport some bling in her day (butterfly rings, anyone?) but this rock – worn noticeably on her engagement finger this weekend – is makin’ a statement! I mean seriously, who could she possible be engaged too? The number one singer has been linked to Nick Cannon recently, but he’s a newly single guy who can’t possibly be looking to settle down right this second. Our guess: she’s engaged to herself. I mean seriously, once you’ve been with Mariah, how could you be with anyone else?
