Mia Regan took to Instagram on Friday as she shared a sweet tribute to celebrate her boyfriend Romeo Beckham’s 21st birthday.

The model, 20, didn’t hold back from showing her unconditional love on his special day by sharing a slew of throwback snaps.

She captioned her latest post: ‘HAPPIII BIRTHDAY SWEET RO ROOOOO❤️‍��❤️‍��❤️‍��❤️‍�� my love to you = 5eva xxxx. Thank you for being the best xxxxx.’

Mia sent fans into overdrive as she posted a few sweet pictures beaming with her loved one, starting with a black and white sequence of photo booth snaps.

The three snaps captured some very spontaneous moments, as the couple shared kisses and showed off a funny face.

Romeo appeared to be over the moon as he replied under the post: ‘I love youuuu ♥️,’ and Mia added: ‘@romeobeckham ❤️❤️❤️kiss.’

The model shared another snap from one of their adventurous trips, capturing them in a sweet hug in the middle of a rocky landscape.

The following snap – also from one of their summer trips – showed Romeo hugging Mia from behind as he lays his head on her shoulder, while the duo appeared to be in company of a dog.

In the snap Mia showed off her blonde extensions and a brown and blue bikini set.

The model also shared another selfie as the duo holds an ice-cream cup, followed by a portrait of Romeo as he donned a beige sweatshirt and a Puma cap.

Another snap showed the couple in a festival field as Mia hugged Romeo from behind, highlighting the sweet height difference.

Mia also shared a mirror selfie as her and Romeo are captured striking a pose for the camera.

Mia showed off her sense of style with a beige denim skirt and a black pinstripe shirt, and accessorised with an edgy metallic necklace and chunky rings.

Meanwhile Romeo opted for a total black look, as he beamed to Mia wrapping his arm around her and holding hands.

Another snap from the carousel captured the couple in black and white, as Romeo holds her tight in a sweet hug and Mia shows off a funny grim with her tongue out.

To finish off the iconic tribute, Mia shared a funny picture of Romeo as he wears a white cowboy hat.

After struggling with the long-distance relationship back in May, the couple appeared to be going stronger than ever.

The son of David and Victoria Beckham officially ditched his US football career in June, opting instead to join the west London side Brentford B over his father’s club Inter Miami CF II.

The football star has been on loan of the English team since January, and has decided to prioritise being close to Mia, as the long-distance was too ‘difficult’ for the couple.

‘Despite their best efforts, it really took its toll and they split up for a while. But when he returned to the UK on loan to Brentford they rekindled things, and things are going really well,’ a source told The Mirror.

But it appears all is going well for the two lovebirds, as just last month the football star openly gushed over Mia saying ‘crazy how lucky I am’.

In August Romeo took to Instagram to share a throwback snap of them at Glastonbury Festival last month, putting on a very loved-up display.

They looked as smitten as ever as Mia is captured laying down across Romeo and the pair shared a kiss in a very cosy display of affection.

In the snap, Romeo went shirtless in a pair of pink tie-dye shorts and sported a pair of fluorescent green Oakley sunglasses.

Meanwhile, Mia sported a blue bikini top and colour coordinated checkered shorts as they soaked up the sun during the annual music festival.

In an accompany caption, Romeo sweetly gushed over his girlfriend as he wrote: ‘Crazy how lucky I am with this person 🙂 @mimimoocher.’

Romeo and Mia started dating in May 2019, but it wasn’t until a year later until Mia first appeared on Romeo’s Instagram when they made their relationship ‘red carpet official’.

However, the pair then sadly parted ways in July 2022 after a three-year romance, with Romeo deleting all traces of Mia from his Instagram.

But just four months later, Romeo hinted at their reconciliation with a conveniently-cropped photo where he received a kiss on the cheek from a mystery love interest.

He then finally confirmed that they had rekindled their romance as they were both seen on a night out with their friends to celebrate Mia’s 20th birthday.

Romeo also gushed over the ‘gorgeous’ model on her big day by sharing some old shots in a sweet birthday tribute.

During their brief time apart, Mia stayed friendly with his family and even collaborated with his mother Victoria Beckham on her self-titled fashion brand.

Since getting back together, the pair appear to be closer than ever and were seen packing on the PDA as they attended Wimbledon in July.
