Nick Jonas is one lucky man.

Because His stunning girlfriend Olivia Culpo, who took the title of Miss Universe in 2012, rocked the red carpet on Sunday as she stepped out in a racy white fishtail dress - which showed off a lot of skin.

With sheer panels running up past her thighs and a plunging neckline, the 22-year-old model was spotted looking loved up with her Disney channel beau.

Letting her statement dress do the talking, Olivia teamed her look with a simple bracelet and a huge sparkling ring.

The model opted for simple make-up, accentuating her eyes with a smoky look, while keeping her straight brunette locks away from her face.

Meanwhile Nick, who accompanied his girlfriend to the 63rd annual Miss Universe awards at the Trump National Hotel in Florida, wore a two-tone suit teamed with a polka-dot shirt and black skinny jeans.

The 22-year-old singer finished his look off with a bright white pair of pumps, ahead of his performance at the event on Sunday evening.

Nick even serenaded his stunning girlfriend mid-song, something Olivia seemed to love.

Posting on Instagram she wrote: "Best part of tonight. Being serenaded by this stud #MissUniverse2015 @nickjonas".

Aww, young love.
