She checked herself into rehab last year after suffering from anxiety and stress.
But fast forward seven months and LeAnn Rimes looks the picture of health - both physically and emotionally.
The 30-year-old showed off her curves in a bikini and shorts as she threw her arms up in the air with glee on Sunday while enjoying a short break in South Beach, Florida.

The rare weekend off will be short lived for LeAnn, who is scheduled to sing at the Sunrise Theatre in the central Florida town of Fort Pierce on Sunday.
On Friday she visited other cities on the Gulf Coast including New Orleans, Louisiana and Biloxi, Mississippi.
With her new album Spitfire out in just a few days, LeAnn has a heavy touring schedule ahead of her.
