Romeo Beckham cheekily grabs model girlfriend Mia Regan’s bottom as they celebrate her 21st birthday after he got a tattoo tribute to mark the occasion

Romeo Beckham and girlfriend Mia Regan looked more in love than ever as they posed for Instagram photos while celebrating her 21st birthday at Bacchanalia restaurant in Mayfair on Monday.

The pair cozied up for sweet snaps after the footballer, 21, unveiled a tattoo tribute to the model to mark her birthday weekend.

Cheeky Romeo grabbed Mia’s bum in one image as he made an animated facial expression for the camera.

Mia looked fantastic in a sleeveless black top with high neckline from Susamusa, which she paired with a matching skirt.

It comes after Romeo unveiled a tattoo tribute to long-term love Mia to mark her 21st birthday this weekend.

The beauty, who goes by the nickname Mimi Moocher, was the subject of the Beckham lad’s latest body art – with the word ‘Mooch’ on his bicep, which she proudly shared with her followers as they dined at Bacchanalia restaurant in Mayfair.

The Beckham clan is known for their love of tattoos and Romeo has wasted no time in catching up on the three-figure body art of his father David and brother Brooklyn.

Romeo’s tribute to his girlfriend appears to be a learned behavior as his older brother, 24, has a whopping 70 tattoos dedicated to his wife Nicola Peltz.

The couple have been dating since 2019 and after a brief breakup last summer, they reunited and are now stronger than ever.

Last year they confirmed their split and Romeo deleted all traces of London model Mia from his Instagram.

It is believed that the toll of a long-distance relationship ultimately contributed to the breakup with Romeo pursuing a football career in Miami, Florida.

Mia and Romeo celebrated their three-year anniversary shortly before announcing their split last year.

At the time, she remained friends with his family and even worked with his mother Victoria Beckham on her self-titled fashion brand.

Sources confirmed to MailOnline that the couple split due to the pressure caused by their conflicting work schedules, with Romeo spending much of his time in the United States as he pursued a football career.

Clearly stronger than ever, the happy couple shone in a series of snaps that Romeo shared with his 3.9 million Instagram followers.

In an accompanying caption, he wrote: “HAPPY 21st beautiful girl, I love you so much @mimimoocher.”

Last month, the Beckham boys all got ‘Brotherhood’ engraved on different parts of his body, in their first group tattoo.

The eldest of the three, Brooklyn, chose to have his new tattoo on his leg over his dancing lady body art, while Romeo also had his on his leg over his eagle ink, while Cruz chose to have his to have on his hand.

London-based fine line tattoo artist Pablo, also known as Certified Letter Boy, took to his Instagram page on Friday to share some photos of the intricate designs.

The photos showed the boys standing with their arms draped over each other’s shoulders, while some showed off the new tattoos.

Cruz happily posed for a photo as Pablo went to work, with the teen jokingly wincing in pain as the needle hit his hand.

In addition to their matching ink, Romeo also got a tattoo during their visit to the salon and took to Instagram to show off the results.

He shared a photo of his back with a new quote tattoo on his shoulder blade, as he follows in his father’s footsteps with his script tattoos.

The quote from the late fashion designer Virgil Abloh said, “Life is so short, you can’t waste a day subscribing to what someone thinks you can do instead of knowing what you can do.”
