Jordin Sparks truly dazzled at the premiere of her new film Sparkle Thursday night at the Grauman’s Chinese Theater in Hollywood, Calif.

The 22-year-old singer-actress donned a strapless white gown covered in gems, paired with silver peep-toe pumps, as she graced the red carpet to promote her new film — now playing in theaters.

Sparks looked simply stunning in the couture which featured a glimpse of her impressive slim down.  The American Idol season six winner has lost approximately 50 pounds since 2007.

And who was her arm candy for the night?

The Hollywood starlet took her lucky parents to the premiere since her boyfriend, singer Jason Derulo, was busy working in Australia.

Sparks, alongside her Sparkle co-stars — Nigerian actress Carmen Ejogo, One Life to Live’s Tika Sumpter and The Voice coach Cee Lo Green — were all smiles on the red carpet, but it was’t just the film they were there to celebrate. Sadly, in February, the cast of Sparkle lost its star Whitney Houston — and the world lost an icon.

The star-studded premiere of Houston’s last film turned into a celebration of her life and career. As reported by The Hollywood Reporter, before the film started, her mother Pat Houston went on stage and adressed the audience. “I can assure you that Whitney is here celebrating right now.”

As for Sparks, the brunette recently flaunted her trim figure on the cover of Shape magazine, wearing an electric blue bikini.

On her weight struggles, Sparks confessed, “I knew I had a long road ahead of me. I was barely working out, and my diet was a mess. I had to address when, what, and how much I was eating.”

“I just wanted to be healthy. I remember thinking, ‘I’m in my prime. I should be happy and fit.'”

Referring to her twenties as her prime, that was the moment Sparks realized she had to make a lifestyle change, and it sure has paid off.
