Demi Lovato showed off her fit bikini body in Vancouver amid rumors she’s dating UFC superstar Luke Rockhold.

Demi posted an Instagram photo of herself looking stunning in a strapless patterned bikini during a yachting trip in Vancouver, British Columbia.

Lovato, who has battled anorexia, bulimia, bipolar depression, alcoholism and drug addiction, looks better than she has in years, thanks to boxing and mixed-martial arts workouts.

Demi, 24, recently began dating Luke Rockhold, a 31-year-old mixed martial arts star who competes in the Ultimate Fighting Championship league.

Sources told TMZ Lovato met Rockhold earlier this year while training at Unbreakable Gym in Los Angeles.

The 5-foot-2 Demi and the strapping 6-foot-3 Luke reportedly hit it off right away, and have been secretly dating ever since.

For now, the romance is long-distance as Lovato is traveling with Nick Jonas on his Future Now Tour in support of his third solo album, Last Year Was Complicated.

Lovato has been doing well since going to rehab in 2010 to seek help for her mental illnesses and eating disorders.

Demi treats her bipolar disorder with medication and therapy, but admits she still struggles with depression, Celebrity Health Fitness reported.

Lovato, who was addicted to alcohol, cocaine and marijuana, suffered from the eating disorders anorexia and bulimia since age 8, and at one point starved herself down to 88 pounds.

Demi finally ended the vicious cycle of bingeing and purging after realizing it could permanently damage her body and her voice.

Demi said she wants to be a role model for other young girls suffering from similar problems.

Looking back, she’s glad she went public with her issues because her experiences may be able to help others.

“[I want to be a] role model,” she said. “There was nobody out there for me to look at and say this is unhealthy.

Lovato, who recently dropped her fifth studio album, Confident, is happy with her progress and has big dreams for her future.

“I’ve done that a lot over the past few years, but it has been so worth it, because the people in my life today inspire me to keep being creative, to have fun, and to be a good person,” said Lovato.

Demi Lovato detailed her harrowing struggles with unhealthy weight loss, drug addiction, anorexia and bulimia in her memoir, Staying Strong: 365 Days a Year.
