The statement dress was sprinkled with gleaming silver trimmings, and cinched around her waist with the help of a silver metallic belt.

Heidi made her way through the brown carpet with a pair of black strappy sandals and posed for photos with her beautiful boyfriend.

The blonde beauty seemed the epitome of glamor as it accentuated her busty neckline with a diamond necklace that left her breathless.

The former Victoria's Secret model designed her blond braids in loose waves with beaches that looked elegantly scruffy after her sunset boat trip to the star-studded charity event.

Heidi complemented her complexion bathed in the sun with a highlighter sweep and a pink lip, and added a splash of color with a bold red pillar box mani-pedi.

Meanwhile, Tom was dressed casually in a white vest and matching pants, and a pair of converse sneakers for the elegant event.

Heidi's bearded boyfriend put on a light gray striped jacket to improve his appearance, and even added a crisp white pocket as a measure.

The two looked wounded as they smiled widely and stood together on the hip while the photographers showed a storm.

The romance between the two Germans seems to be going strong as it was linked for the first time in mid-March.

Heidi and Tom were spotted spending time together in Pasadena, California, where he was filming America's Got Talent.

Despite having fallen in love with someone 17 years younger than her, the model recently returned the age gap and admitted that she does not even think about it.

Speaking with InStyle, she said: "Lately, other people remind me more about my age than me.

"My boyfriend is many years younger than me, and a lot of people question it and ask about it, that's really the only time it seems that age pushes me in the face and I have to give an answer."

She added: "Actually, I do not think so much about that. You have to live a happy life without worrying too much about what people think, because worrying will only give you more wrinkles. "

It is believed to be Heidi's first relationship since separating from art dealer Vito Schnabel, 31, in September after three years together.

She announced the division with the statement: "I think it's important to take time to pause and reflect."

In June, they raised their eyebrows when they portrayed Vito kissing a mysterious brunette in the early hours of London, while Heidi was in New York filming new episodes of Next Top Model of the United States.

Vito then sent a statement to People that said: "The statements that have been made are a misinterpretation of a completely innocent situation."
