Skinny Songstress! Mariah Flaunts Dramatic Weight Loss On Hot Date With Bryan

Mariah Carey flaunted her dramatic weight loss on a date with on-again boyfriend Bryan Tanaka at Dan Tana's in West Hollywood, Calif. last night! RadarOnline.com has exclusively learned that the 47-year-old has lost "30 pounds in 30 days using an extreme cleanse diet and grueling exercise plan!" Needless to say, Tanaka, 34, couldn't keep his hands off the super skinny "Touch My Body" singer! Click through seven super skinny photos of Carey's total body transformation.

Carey rocked a black miniskirt and hot-pink top while out on a hot date with her longtime backup dancer boyfriend! "She looks amazing and she is back to her 20-something weight," a friend of Carey's said.

"Mariah didn't realize how much the weight was holding her down, physically and mentally. Although she started losing weight last year around the holidays, the last 30 pounds was really hard for her to shed," the friend told RadarOnline.com.

As previously reported, Carey allegedly underwent weight loss surgery last year. However, the friend insisted that her new sexy body is also the result of a diet, exercise and a detox!

"Aside from that she really stepped up her workouts with her trainer," the pal said, adding, "And now she feels like it is payback time for all those cruel things that people were saying about her bigger figure last year."
