Bindi Irwin appeared in full Hollywood mode for her brother Robert’s semi-final performance on Dancing With the Stars US on Tuesday.

The 27-year-old looked effortlessly chic in a low-cut, sleeveless black dress, which she paired with stilettos and a matching double-breasted overcoat.

Styling her long hair with a bouncy wave, Bindi sported a glamorous make-up look and accessorised with a fine gold chain pendant necklace and a designer handbag.

Accompanied by her husband Chandler and daughter Grace, Bindi was seen ducking into Robert’s trailer for a surprise visit before he hit the dance floor.

Chandler looked smart in a low-key blue suit, which he paired with a white open-neck shirt and brown boots, while Grace looked cute in a frilly lace dress and white cardigan.

An excited Bindi watched on as Robert scored a perfect 10 from the judges alongside dance partner Witney Carson for their sizzling jive routine.

The result has catapulted Robert into the DWTS US grand final.

It comes after Bindi and her husband celebrated a huge relationship milestone on Friday.

The mother-of-one posted a very sweet tribute to her love on Instagram as she revealed it was the 12th anniversary of the day they met.

She uploaded two loved-up images of the pair, as Chandler, 29, lifted Bindi into his arms during their celebrations.

‘Twelve years ago I met the man of my dreams. Chandler, my heart is yours. Always and forever,’ Bindi captioned the post.

The photos saw the celebrity conservationist dressed in a sparkling strapless black gown dotted with glitter.

Sporting a sleek half-up hairstyle, she and Chandler leaned in close to each other as he held her.

The second picture was slightly more blurry, showing the happy couple laughing as Bindi leaned back in Chandler’s arms.

‘And my heart is yours. I love you so much,’ Chandler wrote in the comments.

The matriarch of the family, Terri Irwin, also left a heartfelt message for the pair, writing: ‘And they lived happily ever after!’

Bindi and Chandler first met in November 2013 when the former professional wakeboarder visited Australia for a sporting competition.

He took a tour of Australia Zoo with Bindi as his guide, and the lovebirds quickly hit it off and kept in touch.

Bindi tied the knot with the Florida-born wakeboarder in an intimate ceremony at the start of the Covid pandemic on March 25, 2020.

The couple welcomed daughter Grace on March 25, 2021, exactly one year after they exchanged vows at Australia Zoo.

The couple are temporarily living in the US as Bindi’s brother Robert competes on Dancing With The Stars.
