Cruz Beckham, 19, packs on the PDA with girlfriend Jackie Apostel, 29, as she displays her surgery scar in a backless top during a family day out on a superyacht in Miami

Cruz Beckham couldn't keep his hands off his girlfriend Jackie Apostel as they packed on the PDA on a superyacht in Miami on Monday. 

Cruz, 19, and Jackie, 29, looked more loved-up than ever as they kissed during the trip out to sea where they were joined by his parents David and Victoria. 

During the outing, Jackie, who is a decade older than Cruz, wore a backless top that displayed the surgical scar on her back, which she recently opened up about.

The couple were seen hugging and kissing each other as they relaxed and soaked up the sun while lying on a deck. 

Jackie was later seen straddling Cruz as the couple kissed while sat at a table inside the boat. 

Cruz cut a casual figure for the day out in a red sleeveless T-shirt which he teamed with black shorts. 

Meanwhile Jackie donned an oversized sports T-shirt before removing it revealing the black strapless top which she teamed with white shorts and a baseball cap. 

Cruz later showed off his abs as he removed his T-shirt while he and his girlfriend lay at the stern of the boat soaking up the sun. 

The couple were joined on the outing by his parents, former footballer David, 49, and fashion mogul Victoria, 51.  

David was spotted wearing a pair of blue swimming shorts and black T-shirt as he chatted away to the couple at the back of the boat. 

Elsewhere during the day, Victoria was seen enjoying a refreshing drink with her youngest son and his girlfriend.  

Cruz and Jackie looked completely smitten with each other as they cosied up while relaxing on a sunbed on the yacht. 

The Beckham's outing comes after Jackie shared a shocking photo of her post-surgery scar on Sunday as she revealed three months ago she had to relearn how to walk after a mystery ordeal.

The songwriter took to her Instagram Story as she posted a picture of an extensive scar down the centre of her back.

While Jackie didn't reveal the details of her surgery she revealed that earlier this year the debilitating surgery meant she could barely stand. 

Reflecting on her recovery she penned: 'Random thought. Wild to think 3 months ago I was relearning to walk and couldn't get up. 

'Physically and mentally I had a hard time, took forever to be ok with myself again especially work and writing wise.'

Pausing for a moment of gratitude she continued: 'Our bodies are awesome and capable of so much. Take a moment to be grateful for ur support systems, own willpower and strength, whatever ur going through. 

'We all know it's ok not to be ok all the time and hope everyone is taking care of themselves as much as possible/taking moments to focus on mental and physical health.' 

Jackie then added: 'Also, check in on ur friends. Sending everyone health hugs and love!' 

MailOnline have contacted the Beckham's representatives for comment.  

Since her operation and recovery Jackie has been putting on a loved up display with Cruz who is a decade younger than the star. 

The pair looked absolutely smitten over the weekend as he twirled her around during a stroll in Miami, before driving her to the airport - where the duo shared a goodbye kiss. 

The couple are believed to have been dating since June, and she joined him last month to support Victoria at her Paris Fashion Week show.

She was spotted numerous times with the Beckhams during Fashion Week and even wore one of Victoria's chic dresses to her runway show. 

Following the catwalk presentation, she took to Instagram to gush: 'the most beautiful show and the most beautiful dress. Congratulations @victoriabeckham'.

Cruz recently revealed how smitten he is with Jackie, as he confessed his love for her on Friday, as she celebrated her 29th birthday.

Sharing a picture of Jackie waiting to blow out her candles to his Instagram Story, he dropped the 'L bomb', as he penned: Happy Birthday xx I love you'.

Jackie and Victoria appear to be getting on well, with the Brazilian showing a remarkable resemblance to the Spice Girl on numerous occasions.

Sporting similar looks, hairstyles, and dresses it seems Victoria could be one of Jackie's style icons.

And it looks like Victoria herself has given Jackie her stamp of approval after the singer recently posed for a mirror photo on Instagram in a sexy, black lace dress that was seemingly given to her by Victoria.

'Hot sauce and hotter outfits. thank u for the laciest dream piece @victoriabeckham,' Apostel wrote in the caption of the Instagram post.

She also included a few other snaps of herself in the stunning, curve-hugging, cut-out outfit in the post, showing herself laughing and smiling while sitting outdoors. 

The dress doesn't currently seem to be available as a part of Victoria Beckham's clothing collection, so it appears that Beckham may have picked it out just for Apostel.

Cruz and Jackie recently joined his sister Harper and mum Victoria to support their football club owner dad David.  

The youngest son of David and Victoria Beckham, brought Jackie, to Florida on Saturday to watch Inter Miami play the New England Revolution at the Chase Stadium.

Cruz was spotted sitting alongside Jackie in the suite at the stadium as they sweetly held hands throughout the match. 

In other snaps the couple were seen cosying up together, with Jackie wrapping her arm around her beau's neck.  

According to HELLO!, the brunette beauty is almost a decade older than Cruz, who turns 20 in February.

They wrote: '[Jackie] was formerly a member of Brazilian girl band Schutz, [and] is nine years her boyfriend's senior. 

'In an Instagram post introducing the members of Schutz shared to Instagram in 2022, Jackie is introduced as being 26 years old, making her 28 now. The star will turn 29 on 18 October'.
