Good for Mariah Carey! Lookin' good here in this pic on the beach showin' off her hard work!

The tally so far, 70lbs! She credits Jenny Craig (shameless plug I'm sure) for the recent change in her lifestyle.

She also told Shape Magazine back in April that, "I used to be able to slim down just by exercising more, but that’s changed. Since having the babies, I realize that 90 percent of losing weight is my diet.”

While we're on the subject...how's that resolution going so far this year?!? ;)
