Showing off her new look on The Tonight Show, fans were quick to complement the singer.

Sources say the 'American Idol' winner - who's mum to daughter River, 3, and son Remington, 1 - brought in experts to help with her overhaul.

"She's been working out with a trainer four times a week."

Kelly has also “cut back” on junk food.

She's now eating a high-protein diet and swaps “sugary treats" for vegetables.

We think she looks amazing!
