Romeo Beckham, 18, shares a sweet snap with nine-year-old sister Harper in Miami

The Beckham family moved to the city of Florida while father David works on his football team, Inter Miami CF.

And Romeo Beckham enjoyed a sweet moment with younger sister Harper, while the two enjoyed a scenic boat ride in Miami on Sunday.

The 18-year-old model looked delighted while stroking the adorable nine-year-old Harper while the pair posed in front of the crystal clear waters.

Romeo showed off his style with a gray zippered jacket and an orange wool hat as he hugged Harper.

Harper looked beautiful in a gray sweatshirt as he smiled at the sweet family photo.

The beautiful Miami skyline was visible in the background as the brothers posed.

The photo comes after Romeo and brother Cruz, 16, made fun of Mom Victoria because of her melancholy expression, her trademark – with the designer amusingly reciprocating with a radiant photo gallery.

VB, 46, was on a mission to show that she can vary her expressions after her children mocked her serious face wearing T-shirts with the logo of her collection with ‘FFS SMILE’ printed on them.

Victoria responded to their joke by comparing several pictures of her smiling, writing a caption: ‘Some evidence I really smile!’, To celebrate International Day of Happiness.

They included a gallery of old photos with her football player husband David, on old family vacations and during work events.

In the blink of an eye, she showed off her autobiography called ‘Learning to Fly’, which was released 20 years ago in 2001.

In another, she had her famous blonde hair cut, which she wore in 2007, and in a separate photo, she was beaming in a bikini and life jacket during an escape.

This happened after Romeu and Cruz posted pictures of them wearing T-shirts with the words ‘FFS SMILE’ on them.

Victoria herself also replaced the images by writing on the side: ‘As a mother, as children’.

Victoria previously told Vogue that the ‘worst question’ she has ever asked is ‘Why do you never smile?’

She joked that she is smiling inside and never smiles: ‘I feel like I have a responsibility to the fashion community.’

The former Spice Girl said earlier that she would look silly if she were seen smiling constantly.

“I smile in family photos,” she told The New York Times in 2013. “When you’re in a position to be paparazzi just walking down the street, you would look a little crazy if you were smiling all the time.”

Earlier this week, Victoria shared a hilarious image of a van number plate that said ‘VB BKRY’ on Saturday, while she joked that ‘I hadn’t been this close to a carbohydrate in years’.

The stylist scoffed at her rigid diets with the crack that the record looked like the word ‘Bakery’.
