The songstress is set to wed Aussie billionaire James Packer, and she plans to look exceptional.
Sitting down with Sharon Osbourne, the 46-year-old admitted she is consciously trying to get back into shape.
"I've been pretty consistent with this bleak diet that I am on," she explained.
Watch a snippet from her interview in the player below. Post continues!
Back in March, Mimi spoke to the Sunday Times of her radical new diet that she credited for her svelte new frame.
"Yes. My diet is very bleak," she told the publication.
"I overuse the word because there is a lot of bleakness going on. My bleak diet is horrendous, but I don't want to tell anyone about it because it's none of their business."
Adding, "I am a pretty insecure person. I just don't want people commenting."
But it seems the music legend is getting more confident in herself, and it is certainly helping that she has clear goal in mind.
Sharon asked her if the wedding is now her main inspiration driving her lifestyle overhaul.
"You know, it was the whole situation that made me want to try and be better for all," she responded. "And then we do have to get fittings and dresses!"
Aside from the all the wedding planning, the diva that is Mariah has a lot happening right now.
The mum-of-two is currently amidst her divorce proceedings, raising her five-year-old twins, Monroe and Moroccan, all while slaying her Las Vegas residency.
And let's not forget about her upcoming eight-part documentary, Mariah's World!
"There's a lot on my plate!"
